Product details
Overview
MAX4323EBT-T from Maxim Integrated is a single-channel, rail-to-rail input/output operational amplifier in a 6-bump UCSP package, featuring 5MHz gain-bandwidth, 650µA quiescent current, ±700µV offset voltage (typ), and 25µA shutdown current. It operates from 2.4V to 6.5V single supply and drives 250Ω loads - ideal for precision signal conditioning in battery-powered data-acquisition systems.
For engineers reviewing the MAX4323EBT-T datasheet, MAX4323EBT-T pinout, MAX4323EBT-T application, or MAX4323EBT-T equivalent, this page delivers verified electrical specs, UCSP package layout guidance, shutdown timing behavior, rail-to-rail I/O performance at low voltage, and real-world design considerations for portable instrumentation and PA biasing circuits.
Technical Context
The MAX4323EBT-T uses a dual-input-stage architecture (NPN + PNP) enabling true rail-to-rail input common-mode range (VEE to VCC) without phase reversal on overdrive. Its unity-gain-stable output stage supports capacitive loads up to 500pF and delivers full swing into 250Ω with <350mV headroom from rails at 5V.
Shutdown control (SHDN pin) enables independent disable with high-impedance outputs and reduces ICC to 25µA (typ) at 25°C - critical for intermittent-sampling systems. Input bias current polarity flips near VCC/2, requiring matched source impedances to minimize offset error.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 5MHz - supports stable unity-gain amplification of signals up to ~3MHz with minimal phase lag. |
| Supply Voltage Range | 2.4V to 6.5V single supply - compatible with Li-ion, 3.3V, and 5V systems without level-shifting. |
| Quiescent Current | 650µA per amplifier (typ at 2.4V) - enables >100-hour operation on 100mAh coin cells in active mode. |
| Input Offset Voltage | ±700µV (typ at +25°C) - ensures <1.4mV total error in 2V full-scale sensor interfaces. |
| Output Voltage Swing | VOL ≤ 200mV above VEE, VOH ≥ VCC − 200mV (RL = 250Ω) - delivers >92% of rail-to-rail dynamic range at full load. |
| Shutdown Current | 25µA (typ) - reduces standby power by 26× vs active mode, enabling µA-level system sleep states. |
| Slew Rate | 2V/µs - settles 2V steps in ≤2.0µs to 0.01%, suitable for fast-settling ADC front-ends. |
Pinout & Package
The MAX4323EBT-T is housed in a 6-bump UCSP (Ultra-Compact Silicon Package) measuring 1.5mm × 1.5mm with 0.5mm bump pitch. Bumps are on the bottom side; orientation key is marked "AAW" on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A2) | VEE | Negative supply / ground reference - must be connected directly to low-impedance ground plane. |
| 2 (A1) | IN− | Inverting input - high-impedance node; requires matched trace length and source impedance to IN+. |
| 3 (B1) | IN+ | Noninverting input - rail-to-rail CMVR enables direct connection to sensors operating near supply rails. |
| 4 (B2) | OUT | Amplifier output - capable of sourcing/sinking ±20mA; stable driving 500pF capacitive loads. |
| 5 (A3) | VCC | Positive supply - requires local 0.1µF ceramic + 1µF bulk bypass within 2mm of bump. |
| 6 (B3) | SHDN | Active-low shutdown enable - internal 1µA pull-up; driven low to enter 25µA standby with Hi-Z output. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Operates with inputs from VEE to VCC - eliminates level-shifting for 0–3.3V sensor outputs. |
| No phase reversal on overdrive | Prevents latch-up or erroneous output during input transients beyond rails - critical for fault-tolerant designs. |
| Capacitive-load stability | Stable with up to 500pF directly on output - avoids external isolation resistors in many filter or cable-drive applications. |
| Low-power shutdown mode | Reduces ICC to 25µA while placing OUT in high-impedance state - enables seamless integration into power-gated subsystems. |
| Unity-gain stability with 500pF | Eliminates need for gain-setting compensation in unity-gain buffers - simplifies PCB layout and BOM. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-channel, low-power, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9001IDBVR | Lower 0.15mV offset (max), 1MHz GBWP, SOT23-5 package, no shutdown pin. | Lacks SHDN functionality; better for ultra-precision DC apps where bandwidth <1MHz suffices. | Select when offset-critical sensor front-ends require guaranteed <150µV max and shutdown is handled externally. |
| MCP6001UT-E/OT | Higher 1.5V/µs slew rate, 1MHz GBWP, SOT23-5, no shutdown, 100nA input bias. | Optimized for cost-sensitive, non-shutdown applications with moderate speed requirements. | Choose for high-volume portable devices where 1MHz bandwidth and lowest unit cost outweigh shutdown need. |
Compared with TLV9001IDBVR and MCP6001UT-E/OT, the MAX4323EBT-T uniquely combines 5MHz bandwidth, integrated shutdown, and UCSP footprint - making it optimal for space-constrained, intermittently active instrumentation where both speed and ultra-low standby power are mandatory.

FAQ
What is the maximum capacitive load the MAX4323EBT-T can drive stably?
The MAX4323EBT-T is unity-gain stable with capacitive loads up to 500pF without external compensation. This is confirmed in the datasheet's Typical Operating Characteristics (Figure 4) and Applications Information section. Driving larger loads may require an isolation resistor (e.g., 39Ω) in series with the output, as shown in Figure 6. Stability margin degrades beyond 500pF, risking overshoot or ringing in transient response - always verify with actual board layout and load conditions.
Does the MAX4323EBT-T have rail-to-rail input capability across the full temperature range?
Yes, the MAX4323EBT-T maintains rail-to-rail input common-mode voltage range (VEE to VCC) from −40°C to +85°C, as specified in the DC Electrical Characteristics table under "Common-Mode Input Voltage Range" with CMVR = VEE to VCC across all temperatures. This is enabled by its dual NPN/PNP input stage architecture, which remains functional across the full operating range without degradation in input range or phase reversal.
How does the shutdown function behave on the MAX4323EBT-T?
When the SHDN pin is pulled low (<0.8V), the MAX4323EBT-T enters shutdown mode: supply current drops to 25µA (typ), and the output enters a high-impedance state. The internal 1µA pull-up allows floating SHDN to default to active (enabled). Turn-on time is 1µs (typ), and shutdown delay is 0.2µs (disable). These values are measured per AC Electrical Characteristics and validated in Figures 11–12 of the datasheet.
What is the typical input bias current of the MAX4323EBT-T, and how does it vary with input voltage?
The MAX4323EBT-T exhibits bipolar input bias current that changes polarity near VCC/2 due to its dual-input-stage architecture. At VCM = VEE or VCC, typical IB is ±50nA (+25°C); at VCM = VCC/2, it crosses zero. This behavior is documented in Figure 9 and the Applications Information section. To minimize offset error, match source impedances seen by IN+ and IN−, especially in high-impedance sensor interfaces.
Is the MAX4323EBT-T pin-compatible with other members of the MAX432x family?
No - the MAX4323EBT-T (6-bump UCSP) has a unique pinout incompatible with SOT23-5, SOT23-6, µMAX, or SO packages used by other MAX432x variants. Pin mapping differs significantly: UCSP uses bumps A1–A3/B1–B3 for IN−, IN+, VEE, VCC, OUT, SHDN, while SOT23-6 places SHDN on pin 5 and lacks dedicated VEE (shared with GND). Physical and electrical incompatibility means PCB redesign is required for substitution.
