General Description The MAX4322/MAX4323/MAX4326/MAX4327/MAX4329 family of operational amplifiers combines wide bandwidth and excellent DC accuracy with Rail-to-Rail® operation at the inputs and outputs. These devices consume only 650µA per amplifier and operate from either a single sup- ply (2.4V to 6.5V) or dual supplies (±1.2V to ±3.25V). These unity-gain-stable amplifiers are capable of driving 250Ω loads and have a 5MHz gain-bandwidth product. The MAX4323 and MAX4327 feature a low-power shutdown mode that reduces supply current to 25µA and places the outputs in a high-impedance state. With their rail-to-rail input common-mode range and output swing, these amplifiers are ideal for low-voltage, single-supply operation. In addition, low offset voltage and high speed make them the ideal signal-condition- ing stages for precision, low-voltage data-acquisition systems. The MAX4323 is offered in a small 6-bump chip-scale package (UCSP™). The MAX4322/MAX4323 are also available in space-saving SOT23 packages. ________________________Applications Battery-Powered Data-Acquisition Instruments Systems RSSI Systems Signal Conditioning PA Biasing Portable Equipment Low-Power, Low-Voltage Applications ____________________________Features  6-Bump UCSP Package (MAX4323)  2.4V to 6.5V Single-Supply Operation  Rail-to-Rail Input Common-Mode Voltage Range  Rail-to-Rail Output Voltage Swing  5MHz Gain-Bandwidth Product  650µA Quiescent Current per Amplifier  700µV Offset Voltage  No Phase Reversal for Overdriven Inputs  Drive 250Ω Loads  25µA Shutdown Mode (MAX4323/MAX4327)  Unity-Gain Stable for Capacitive Loads Up to 500pF M A X 4 3 2 2 /M A X 4 3 2 3 /M A X 4 3 2 6 /M A X 4 3 2 7 /M A X 4 3 2 9 Single/Dual/Quad, Low-Cost, UCSP/SOT23, Low-Power, Rail-to-Rail I/O Op Amps ________________________________________________________________ Maxim Integrated Products 1 Pin Configurations 19-1380; Rev 3; 10/02 Ordering Information Rail-to-Rail is a registered trademark of Nippon Motorola, Ltd.

Input Protection Circuit __________Applications Information Rail-to-Rail Input Stage Devices in the MAX4322/MAX4323/MAX4326/MAX4327/ MAX4329 family of high-speed amplifiers have rail-to- rail input and output stages designed for low-voltage, single-supply operation. The input stage consists of separate NPN and PNP differential stages, which com- bine to provide an input common-mode range extend- ing to the supply rails. The PNP stage is active for input voltages close to the negative rail, and the NPN stage is active for input voltages near the positive rail. The input offset voltage is typically below 250µV. The switchover transition region, which occurs near VCC/2, has been extended to minimize the slight degradation in CMRR caused by the mismatch of the input pairs. Their low offset voltage, high bandwidth, and rail-to-rail common-mode range make these op amps excellent choices for precision, low-voltage, data-acquisition systems. Since the input stage switches between the NPN and PNP pairs, the input bias current changes polarity as the input voltage passes through the transition region. To reduce the offset error caused by input bias cur- rents flowing through external source impedances, match the effective impedance seen by each input (Figures 1a, 1b). High-source impedances, together with the input capacitance, can create a parasitic pole that produces an underdamped signal response. Reducing the input impedance or placing a small (2pF to 10pF) capacitor across the feedback resistor improves the response. The MAX4322/MAX4323/MAX4326/MAX4327/MAX4329s’ inputs are protected from large differential input voltages by 1kΩ series resistors and back-to-back triple diodes across the inputs (Figure 2). For differential input volt- ages less than 1.8V, the input resistance is typically 500kΩ. For differential input voltages greater than 1.8V, the input resistance is approximately 2kΩ, and the input bias current is determined by the following equation:
