General DescriptionThe MAX4162/MAX4163/MAX4164 are single/dual/quad, micropower operational amplifiers that combine an exceptional bandwidth to power consumption ratio with true rail-to-rail inputs and outputs. They consume a mere 25μA quiescent current per amplifier, yet achieve 200kHz gain-bandwidth product and are unity-gain stable while driving any capacitive load. The MAX4162/MAX4163/MAX4164 operate from either a single supply (2.5V to 10V) or dual supplies (±1.25V to ±5V), with an input common-mode voltage range that extends 250mV beyond either supply rail. These amplifiers use a proprietary architecture to achieve a very high input common-mode rejection ratio without the midswing nonlinearities present in other rail-to-rail op amps. This architecture also maintains high open-loop gain and output swing while driving substantial loads.The combination of excellent bandwidth/power performance, single-supply operation, and miniature footprint makes these op amps ideal for portable equipment and other low-power, single-supply applications. The single MAX4162 is available in 8-pin SO and space-saving 5-pin SOT23 packages. The MAX4163 is available in an 8-pin ultra chip-scale package (UCSP™) and an 8-pin μMAX® or SO package. The MAX4164 is available in a 14-pin SO package.

Pin Description
Typical Operating Characteristics (continued)
Applications InformationRail-to-Rail Inputs and OutputsThe MAX4162/MAX4163/MAX4164 input common-mode range extends 250mV beyond each of the supply rails, providing a substantial increase in dynamic range over other op amps (even many of those referred to as rail-to-rail). Although the minimum operating voltage is specified at 2.5V, the devices typically provide full rail-to-rail operation below 2.0V (Figure 1). These amplifiers do not suffer from midswing common-mode-rejection degradation or cross-over nonlinearity often encountered in other rail-to-rail
op amps. Extremely low, 1.0pA input bias current makes these devices ideal for applications such as pH probes, electrometers, and ionization detectors. They are also protected against phase reversal (inferred from CMRR test) and latchup for input signals extending beyond the supply rails. The output stage achieves a lower output impedance than traditional rail-to-rail output stages, providing an output voltage range that typically swings within 150mV of the supply rails for 1mA loads. This architecture also maintains high open-loop gain and output swing while driving substantial loads.
Output Loading and StabilityThese devices drive 1mA loads to within 150mV of the supply rails while consuming only 25μA of quiescent current. Internal compensation allows these amplifiers to remain unity-gain stable while driving any capacitive load (Figure 2).
Internal Charge PumpAn internal charge pump provides two internal supplies typically 2V beyond each rail. These internal rails allow the MAX4162/MAX4163/MAX4164 to achieve true rail-to-rail inputs and outputs, while providing excellent common-mode rejection, power-supply rejection ratios, and gain linearity.These charge pumps require no external components, and in most applications are entirely transparent to the user. Two characteristics may be visible to the user, depending on the application:

1) The on-board charge pumps generate a small amount of 700kHz switching noise at the op amp’s output. The amplitude of this noise is typically 100μVP-P. The noise is not referred to the input, and is independent of amplifier gain. The charge-pump switching frequency is well beyond the amplifier’s 200kHz bandwidth, and is therefore unnoticeable in most applications.
2) The charge pumps typically require up to 20μs on power-up to fully energize the internal supply rails (Figure 3).
Power Supplies and LayoutThe MAX4162/MAX4163/MAX4164 are guaranteed to operate from a single 2.5V to 10.0V power supply, but full rail-to-rail operation typically extends below 2V. For single-supply operation, bypass the power supply with a 1μF capacitor in parallel with a 0.1μF ceramic capacitor. If operating from dual supplies, bypass each supply to ground.Good layout improves performance by decreasing the amount of stray capacitance at the op amp’s inputs and output. To decrease stray capacitance, minimize both trace and external component lead lengths, and place external components close to the op amp’s pins.
UCSP Package ConsiderationFor general UCSP package information and PC layout considerations, please refer to the Maxim Application Note (Wafer-Level Ultra-Chip-Board-Scale-Package).
UCSP ReliabilityThe UCSP represents a unique packaging form factor that may not perform equally to a packaged product through traditional mechanical reliability tests. UCSP reliability is integrally linked to the user’s assembly methods, circuit board material, and usage environment. The user should closely review these areas when considering use of a UCSP. Performance through operating life test and moisture resistance remains uncompromised as it is primarily determined by the wafer-fabrication process. Mechanical stress performance is a greater consideration for a UCSP package. UCSPs are attached through direct solder contact to the user’s PC board, foregoing the inherent stress relief of a packaged product lead frame. Solder joint contact integrity must be considered.Table 1 shows the testing done to characterize the UCSP reliability performance. In conclusion, the UCSP is capable of performing reliably through environmental stresses as indicated by the results in the table. Additional usage data and recommendations are detailed in the UCSP application note, which can be found on Maxim’s website at www.maximintegrated.com.
