Product details
Overview
The MAX40006ANT+T from Maxim Integrated is a micropower, rail-to-rail input/output operational amplifier with active-low shutdown, designed for ultra-low-power precision signal conditioning in space-constrained battery-powered systems. It delivers 300kHz gain-bandwidth, 4.5μA supply current (typ), 1pA input bias current (typ), and operates from 1.7V to 5.5V - enabling use in wearable fitness devices and portable medical sensors where quiescent power and input leakage are critical.
For engineers reviewing the MAX40006ANT+T datasheet, MAX40006ANT+T pinout, MAX40006ANT+T application, or MAX40006ANT+T equivalent, this page provides verified circuit role, package mapping, thermal performance, shutdown timing, and real-world capacitive-load stability guidance - all confirmed for the 6-bump WLP variant specified over –40°C to +125°C.
Technical Context
The MAX40006ANT+T employs a BiCMOS process with parallel n-channel/p-channel input stage to achieve rail-to-rail common-mode range (–0.05V to VDD + 0.05V) and output swing within 5mV of both rails under 100kΩ load. Its unity-gain stability supports direct use in buffer configurations without external compensation.
It integrates back-to-back input diodes for ±(VDD + 0.3V) differential voltage protection and features an active-low SHDN pin that reduces supply current to 100nA (typ) while placing the output in high-impedance state - with 2µs shutdown entry and 35µs wake-up delay at VDD = 5.5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 300kHz - enables stable unity-gain buffering of DC–300kHz signals with minimal phase margin degradation. |
| Supply Current | 4.5μA (typ) at 3.6V - allows >1-year operation on a single CR2032 coin cell in always-on sensor front-ends. |
| Input Bias Current | 1pA (typ) at +25°C - preserves accuracy in high-impedance pH, photodiode, or electrochemical sensor interfaces. |
| Input Offset Voltage | ±0.2mV (typ) - supports sub-mV-level signal amplification without trimming in portable medical analog front-ends. |
| Rail-to-Rail I/O | Input CM range extends 50mV beyond rails; output swings to within 5mV of VDD/GND at 100kΩ - maximizes dynamic range in 1.8V/3.3V systems. |
| Shutdown Current | 100nA (typ) - reduces system standby power by >99% versus active mode, critical for intermittent-sampling wearables. |
| Operating Temperature | –40°C to +125°C - qualified for automotive cabin modules and industrial portable test equipment. |
Pinout & Package
MAX40006ANT+T uses a 0.73mm × 1.07mm, 6-bump wafer-level package (WLP) with 0.35mm pitch, optimized for ultra-dense PCB layouts in wearables and hearing aids.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | IN+ | Noninverting input - high-impedance node (≥1GΩ) accepting signals from photodiodes or electrode interfaces without loading. |
| A2 | IN− | Inverting input - matched to IN+ for low offset; internal back-to-back diodes protect against ±(VDD + 0.3V) transients. |
| A3 | OUT | Amplifier output - drives capacitive loads ≤30pF directly; high-impedance during SHDN for safe multiplexing. |
| B1 | SHDN | Active-low shutdown control - logic-low (≤0.3×VDD) disables amplifier and reduces IDD to 100nA. |
| B2 | VDD | Positive supply - accepts 1.7V–5.5V single supply; bypass with 0.1μF capacitor required for noise immunity. |
| B3 | GND | Analog ground reference - must be low-impedance connection to minimize PSRR degradation and offset drift. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Extends 50mV beyond VDD/GND - enables direct sensing of battery voltage or thermistor outputs near supply rails. |
| Ultra-low 1pA input bias current | Maintains <0.1% gain error in 10MΩ source impedance circuits - essential for high-resistance biosensor front-ends. |
| 35µs power-up settling time | Enables rapid wake-from-shutdown sampling in duty-cycled IoT nodes without sacrificing DC accuracy. |
| Stable with 30pF capacitive load | Eliminates need for isolation resistors in compact PCB layouts with short traces to ADC inputs or filters. |
| High-impedance output in shutdown | Allows safe sharing of output node across multiple op amps or analog switches without contention. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar micropower rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV8801DRYR | Lower GBW (170kHz), higher input bias current (10fA typ), no shutdown function, same 6-bump WLP footprint. | Lacks active shutdown - unsuitable for duty-cycled systems requiring sub-μA standby. | Select when shutdown is unnecessary and lower bandwidth suffices for sensor signal bandwidth. |
| OPA316IDBVR | Higher supply current (400μA), wider supply range (1.8V–5.5V), includes shutdown, but larger SOT-23-6 package (2.9mm × 1.6mm). | Not suitable for ultra-compact wearables due to 4× larger PCB area vs. MAX40006ANT+T's 0.73mm × 1.07mm WLP. | Choose when higher drive strength or better AC performance justifies larger layout footprint. |
Compared with TLV8801DRYR and OPA316IDBVR, the MAX40006ANT+T uniquely combines 300kHz GBW, 1pA input bias, 100nA shutdown current, and 0.77mm² WLP packaging - making it the only option meeting simultaneous requirements for ultra-low-power, high-precision, and space-constrained portable medical and wearable designs.

FAQ
What is the maximum capacitive load the MAX40006ANT+T can drive without oscillation?
The MAX40006ANT+T is unity-gain stable up to 30pF capacitive load. When configured for minimum gain of 10V/V, it supports up to 250pF. For loads between 30pF and 200pF in unity-gain, adding a 5Ω–50Ω isolation resistor in series with the output restores stability - verified in the MAX40006ANT+T datasheet Figure 2 and Typical Operating Characteristics section.
Does the MAX40006ANT+T require external power-supply decoupling?
Yes - the MAX40006ANT+T requires a 0.1μF ceramic capacitor placed as close as possible between VDD and GND pins. This decoupling minimizes supply noise coupling into the amplifier's input stage and prevents instability, especially during shutdown transitions. Layout guidelines in the MAX40006ANT+T datasheet emphasize placement proximity to the WLP package.
How does the MAX40006ANT+T behave during shutdown mode?
In shutdown mode (SHDN ≤ 0.3×VDD), the MAX40006ANT+T reduces supply current to 100nA (typ) and places its output in high-impedance state. However, due to internal back-to-back diodes, the output voltage may float to approximately one diode drop below the IN+ voltage in unity-gain buffer configuration - documented in MAX40006ANT+T Figures 4–8.
Is the MAX40006ANT+T pin-compatible with other variants in the MAX40006 family?
No - the MAX40006ANT+T (6-bump WLP) has different pin mapping and physical dimensions than the MAX40006AUT+ (6-pin SOT-23). While both share identical electrical functionality and pin functions, their land patterns, thermal characteristics (θJA = 98°C/W vs. 230°C/W), and mechanical mounting are incompatible. PCB redesign is required for substitution.
What is the input common-mode voltage range specification for the MAX40006ANT+T?
The MAX40006ANT+T guarantees an input common-mode voltage range of –0.05V to VDD + 0.05V across –40°C to +125°C - confirmed in the Electrical Characteristics table. This rail-to-rail capability allows direct interfacing with sensors whose output spans the full supply range, such as resistive temperature detectors or battery voltage dividers.
