Product details
Overview
The MAX40007ANT+T from Maxim Integrated is a single nanoPower CMOS operational amplifier optimized for ultra-low quiescent current (700nA typical), rail-to-rail output, and ground-sensing inputs. It operates from 1.7V to 5.5V, delivers 20kHz gain-bandwidth, and features ±0.3mV input offset voltage - making it ideal for continuous-sense signal conditioning in battery-powered wearable health monitors.
For engineers reviewing the MAX40007ANT+T datasheet, MAX40007ANT+T pinout, MAX40007ANT+T application, or MAX40007ANT+T equivalent, this op amp is selected for precision, sub-1µA supply current, wide supply range compatibility with 1.8V/3.3V microcontrollers, and operation across -40°C to +125°C industrial temperature range.
Technical Context
This op amp uses BiCMOS process technology to achieve ultra-low input bias current (±40pA typical) and low input capacitance (1.5pF), enabling high-impedance sensor interfacing without significant loading error. Its unity-gain stability and 20pF capacitive load drive capability support robust buffer and filter stages in compact analog front-ends.
The device implements ground-sensing input architecture with common-mode range extending to VSS −0.1V, eliminating need for level-shifting in single-supply systems. Input protection diodes and internal ESD structures ensure reliability in portable medical and fitness devices exposed to handling stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 700nA typical at +25°C - enables >10-year battery life in coin-cell-powered wearables. |
| Gain-Bandwidth Product | 20kHz - sufficient for DC–20kHz biosignal amplification (ECG, PPG) without excessive noise. |
| Input Offset Voltage | ±0.3mV typical - supports accurate DC-coupled sensor buffering with <0.1% gain error at 100mV full-scale. |
| Rail-to-Rail Output | Swings within 8mV of rails at 100kΩ load - maximizes dynamic range in 1.8V/3.3V systems. |
| Input Bias Current | ±40pA typical - preserves accuracy when interfacing with >100MΩ electrode or photodiode sources. |
| Operating Temperature | -40°C to +125°C - qualified for automotive cabin, industrial edge, and medical-grade portable equipment. |
| Supply Voltage Range | 1.7V to 5.5V - compatible with Li+ (3.0–4.2V), two-cell alkaline (2.4–3.2V), and regulated 1.8V/2.5V/3.3V rails. |
Pinout & Package
The MAX40007ANT+T is packaged in a 6-bump wafer-level package (WLP), measuring 1.1mm × 0.76mm with 0.35mm bump pitch - among the smallest op amp packages available for space-constrained wearables and implantable sensors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 / Pin 3 | IN+ | Non-inverting input; supports ground-sensing down to VSS −0.1V for direct connection to low-side current shunts or thermistors. |
| A2 / Pin 4 | IN- | Inverting input; internally protected by 12.5kΩ series resistors to prevent input offset drift under differential overvoltage. |
| A3 / Pin 1 | OUT | Amplifier output; rail-to-rail swing enables full utilization of ADC reference voltage in low-voltage systems. |
| B1 / Pin 5 | NC | No connection; internally unconnected - must be left floating or tied to VSS per layout guidelines to avoid parasitic coupling. |
| B2 / Pin 6 | VDD | Positive supply; requires local 0.1µF ceramic bypass capacitor to minimize PSRR degradation at 1kHz. |
| B3 / Pin 2 | VSS | Negative supply; connect directly to system ground in single-supply configurations; forms return path for input bias current. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX40008ANT+T | Same WLP-6 package, but 1.2µA supply current and 40kHz GBW - higher speed at 1.7× supply current. | Preferred for faster sensor interfaces (e.g., pulse oximetry) where 20kHz is insufficient. | Select MAX40008ANT+T only if bandwidth >20kHz is required; otherwise MAX40007ANT+T offers better power efficiency. |
| TLV8801DBVR | 0.5µA supply current, 6kHz GBW, SOT-23-5 package - lower power but significantly reduced bandwidth and no WLP option. | Suitable for slower DC-coupled applications like thermistor conditioning where 20kHz is unnecessary. | Choose TLV8801DBVR for cost-sensitive, non-space-constrained designs requiring <0.5µA current; MAX40007ANT+T preferred for size- and bandwidth-critical wearables. |
Compared with MAX40008ANT+T and TLV8801DBVR, the MAX40007ANT+T uniquely balances 20kHz bandwidth, 700nA current, and 1.1mm × 0.76mm WLP packaging - making it optimal for miniaturized, battery-limited systems needing both precision and responsiveness.

FAQ
What is the maximum capacitive load the MAX40007ANT+T can drive while remaining stable?
The MAX40007ANT+T is unity-gain stable with capacitive loads up to 20pF without external compensation. For larger loads, an isolation resistor (RISO) in series with the output - typically 10Ω to 100Ω - restores phase margin. Layout best practices (short traces, minimized parasitics) are essential to maintain stability at the upper limit of its specified 20pF drive capability. The MAX40007ANT+T datasheet provides RISO vs. CL stability curves for precise selection.
Does the MAX40007ANT+T support true single-supply operation with inputs referenced to ground?
Yes. The MAX40007ANT+T features ground-sensing inputs with a common-mode voltage range extending to VSS −0.1V, allowing direct connection of IN+ or IN− to 0V in single-supply configurations. This eliminates level-shifting circuitry when interfacing with grounded sensors such as thermistors, strain gauges, or current-shunt monitors - a key advantage confirmed in the device's Electrical Characteristics table and Pin Description section for MAX40007ANT+T.
What is the input offset voltage drift over temperature for the MAX40007ANT+T?
The MAX40007ANT+T has a guaranteed input offset voltage temperature coefficient (TCVOS) of 6.4µV/°C to 36.6µV/°C. Over the full -40°C to +125°C range, total offset drift remains within ±4.5mV maximum, as specified in the extended-temperature Electrical Characteristics table. This low drift supports stable DC-coupled performance in environments with wide thermal excursions, such as automotive or outdoor medical devices using MAX40007ANT+T.
Can the MAX40007ANT+T be used as a comparator?
No - the MAX40007ANT+T is not designed or characterized for comparator operation. Its inputs include internal 12.5kΩ protection resistors that cause bias current to increase significantly when differential input voltage exceeds ~1V, degrading response time and accuracy. Maxim recommends dedicated comparators like the MAX40002/3/4/5 for such functions. Using MAX40007ANT+T as a comparator may result in unpredictable propagation delay and increased power consumption.
Is the MAX40007ANT+T RoHS-compliant and lead-free?
Yes. The "+T" suffix in MAX40007ANT+T denotes a lead(Pb)-free and RoHS-compliant package, as explicitly stated in the Ordering Information section of the official datasheet. The WLP-6 package uses lead-free bump metallurgy and conforms to JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for surface-mount assembly. Full compliance documentation is available through Maxim Integrated's quality portal for MAX40007ANT+T.
