Product details
Overview
MAX4322ESA+T from Maxim Integrated is a single-channel, rail-to-rail input/output operational amplifier optimized for low-voltage, precision signal conditioning in battery-powered systems. It delivers 5MHz gain-bandwidth, 650µA quiescent current per amplifier, ±700µV typical input offset voltage (25°C), and full rail-to-rail swing into 250Ω loads - enabling accurate sensor interfacing and data-acquisition front-ends at 2.4V to 6.5V supply.
For engineers reviewing the MAX4322ESA+T datasheet, MAX4322ESA+T pinout, MAX4322ESA+T application, or MAX4322ESA+T equivalent, key selection criteria include its unity-gain stability with up to 500pF capacitive loads, no phase reversal on overdriven inputs, and guaranteed operation across –40°C to +85°C industrial temperature range.
Technical Context
The MAX4322ESA+T employs a bipolar process with complementary NPN/PNP input stage to achieve true rail-to-rail input common-mode range (VEE to VCC) and output swing (within millivolts of rails). Its architecture supports stable operation with capacitive loads up to 500pF without external compensation.
It features a 5MHz gain-bandwidth product and 2V/µs slew rate, delivering fast settling (2.0µs to 0.01%) while maintaining low THD (0.003% at 10kHz) and high PSRR (66–100dB). Input bias current remains below ±150nA (25°C), and CMRR exceeds 62dB over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 5MHz - enables stable closed-loop operation up to ~500kHz at unity gain for anti-aliasing or buffer applications. |
| Supply Current per Amplifier | 650µA at VCC = 2.4V - supports ultra-low-power operation in portable instrumentation and sensor nodes. |
| Input Offset Voltage | ±700µV typical at 25°C - ensures <1mV error in 12-bit ADC front-end designs with 5V reference. |
| Rail-to-Rail I/O | Input CMVR: VEE to VCC; Output swing: within 200mV of rails into 250Ω - maximizes dynamic range in single-supply 3V systems. |
| Capacitive-Load Stability | Stable with up to 500pF - eliminates need for isolation resistors when driving ADC input capacitance or long traces. |
| Operating Supply Range | 2.4V to 6.5V single supply (or ±1.2V to ±3.25V dual) - compatible with Li-ion, coin-cell, and regulated 3.3V/5V rails. |
| Slew Rate | 2V/µs - supports clean 100kHz sine-wave amplification with minimal distortion in signal-chain stages. |
Pinout & Package
MAX4322ESA+T is housed in an 8-pin SO (Small Outline) package, measuring 4.9mm × 3.9mm × 1.75mm (JEDEC MS-012), with gull-wing leads and standard 1.27mm pitch. Pin 1 is marked by a beveled corner or dot.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output - drives loads down to 250Ω with rail-to-rail swing; high-impedance when unused. |
| 2 | IN− | Inverting input - differential pair node; matched impedance critical to minimize bias-current-induced offset. |
| 3 | IN+ | Noninverting input - accepts signals from VEE to VCC; internal protection diodes limit differential input to ±1.8V. |
| 4 | VEE | Negative supply / ground - referenced for single-supply operation; substrate tied to this pin. |
| 5 | N.C. | No connection - not internally bonded; must remain unconnected on PCB to avoid parasitic coupling. |
| 6 | VCC | Positive supply - bypass with 0.1µF ceramic + 1µF tantalum close to pin for noise immunity. |
| 7 | N.C. | No connection - floating; no internal connection; leave unconnected. |
| 8 | N.C. | No connection - unused pin; electrically isolated; do not tie to any net. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Operates with inputs from VEE to VCC - eliminates level-shifting in low-voltage sensor interfaces (e.g., thermistor, bridge). |
| No phase reversal on overdriven inputs | Prevents latch-up or erroneous output polarity during transient overload - critical for robust front-end protection. |
| Unity-gain stable with 500pF load | Enables direct connection to ADC sample capacitors or long PCB traces without added series resistance. |
| Low 650µA quiescent current | Extends battery life in portable medical devices and handheld test equipment operating from 2.4V sources. |
| 700µV max input offset (typ) | Reduces calibration burden in precision 12-bit data-acquisition systems using 5V reference. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462CDR | 2.7–6V supply range; 6.4MHz GBW; 550µA IQ; no shutdown; SO-8 package. | Lacks rail-to-rail input (CMVR starts at 0.2V above VEE); higher offset (1.5mV typ). | Choose for higher bandwidth where input rail-to-rail is not required and cost sensitivity outweighs precision. |
| MCP6002-I/SN | 1.8–6.0V supply; 1MHz GBW; 100µA IQ; rail-to-rail I/O; SO-8 package. | Lower bandwidth limits use in >100kHz signal paths; lower drive capability (6mA short-circuit current vs. 50mA). | Choose for ultra-low-power sensor interfaces where 1MHz GBW suffices and 650µA ICC is excessive. |
Compared with TLV2462CDR and MCP6002-I/SN, the MAX4322ESA+T uniquely balances 5MHz bandwidth, rail-to-rail input/output, and sub-millivolt offset in a standard SO-8 footprint - making it optimal for precision, medium-speed, single-supply data acquisition where dynamic range and fidelity are prioritized over minimum quiescent current.

FAQ
What is the maximum capacitive load the MAX4322ESA+T can drive stably?
The MAX4322ESA+T is unity-gain stable with capacitive loads up to 500pF without external compensation. This is confirmed in the datasheet's AC Electrical Characteristics table and Typical Operating Characteristics (Figure 4). Driving larger loads may require an isolation resistor (e.g., 39Ω) in series with the output, as shown in Figure 6. The MAX4322ESA+T's internal compensation ensures predictable phase margin (>64°) even under these conditions.
Does the MAX4322ESA+T have a shutdown feature?
No, the MAX4322ESA+T does not include a shutdown function. Shutdown is only available on the MAX4323 and MAX4327 variants (e.g., MAX4323EUT-T, MAX4327ESD), which feature a dedicated SHDN pin. The MAX4322ESA+T has no internal shutdown circuitry - all eight pins are either active signal/supply connections or no-connect (N.C.) terminals. Power control must be implemented externally.
What is the input offset voltage specification for the MAX4322ESA+T over temperature?
The MAX4322ESA+T has a maximum input offset voltage of ±3.0mV over the full –40°C to +85°C operating range (DC Electrical Characteristics, TA = –40°C to +85°C). At +25°C, it is ±2.5mV max. The offset voltage drift is ±2µV/°C typical, meaning total drift across the full range adds ≤ ±300µV - contributing less than 0.1% error in a 3V full-scale system.
Can the MAX4322ESA+T operate from a 2.4V single supply?
Yes, the MAX4322ESA+T is fully specified to operate from a 2.4V single supply (VCC = 2.4V, VEE = 0V), as stated in both the General Description and Absolute Maximum Ratings sections. At 2.4V, it maintains 650µA typical supply current, 5MHz gain-bandwidth, and rail-to-rail input/output performance - making it suitable for coin-cell and single-LiFePO₄ powered designs.
Is the MAX4322ESA+T pin-compatible with other op-amps in the SO-8 package?
The MAX4322ESA+T uses a nonstandard SO-8 pinout: Pins 1 (OUT), 2 (IN−), 3 (IN+), 4 (VEE), 5 (N.C.), 6 (VCC), 7 (N.C.), and 8 (N.C.). This differs from industry-standard SO-8 op-amps (e.g., LM358, TL072), which place VCC on pin 8 and VEE/GND on pin 4. Direct replacement requires PCB layout modification - the MAX4322ESA+T is not pin-compatible with generic SO-8 op-amps.
