Product details
Overview
LMC6064AIMX/NOPB from Texas Instruments is a quad-channel precision CMOS micropower operational amplifier optimized for ultra-low-input-bias-current, rail-to-rail output swing (within 10 mV of rails at 100 kΩ), and single-supply operation from 4.5 V to 15 V. It delivers 140 dB open-loop gain, 10 fA typical input bias current, and 100 μV max input offset voltage - enabling high-accuracy signal conditioning in battery-powered instrumentation and sensor front-ends.
For engineers reviewing the LMC6064AIMX/NOPB datasheet, LMC6064AIMX/NOPB pinout, LMC6064AIMX/NOPB application, or LMC6064AIMX/NOPB equivalent, key selection criteria include verified rail-to-rail output drive into 100 kΩ loads, guaranteed 16 μA per amplifier quiescent current, confirmed 14-pin SOIC package mapping, and documented compatibility with photodiode preamplifier, charge amplifier, and portable medical transducer circuits.
Technical Context
The LMC6064AIMX/NOPB uses TI's double-poly silicon-gate CMOS process to achieve ultra-low input bias current (10 fA typ.) while maintaining stable rail-to-rail output swing across temperature and supply voltage. Its input common-mode range includes V−, supporting true single-supply operation down to ground.
Internal compensation ensures stability with capacitive loads when used with recommended pull-up resistors or feedback network adjustments. The device exhibits 100 kHz gain-bandwidth product and 20–35 V/ms slew rate, balancing micropower efficiency with usable bandwidth for precision DC and low-frequency AC applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Input offset voltage | ±100 μV max - supports sub-millivolt DC accuracy in transducer amplifiers and DAC buffers. |
| Quiescent current per amplifier | 16 μA typical - allows four independent channels to operate below 64 μA total, ideal for multi-sensor battery systems. |
| Output swing | Within 10 mV of V+ and V− at 100 kΩ load - delivers full dynamic range in 5 V or 12 V single-supply systems. |
| Open-loop voltage gain | 300–4000 V/mV - ensures high closed-loop accuracy and low gain error in unity-gain and high-gain configurations. |
| Gain-bandwidth product | 100 kHz - supports stable amplification up to ~10 kHz at G = 10, suitable for sensor signal conditioning and filtering. |
| Common-mode rejection | 75–85 dB - maintains accuracy in noisy industrial environments with varying ground references. |
Pinout & Package

|---|---|---|---|
| LMC6084IMX/NOPB | Higher speed: 1.3 MHz GBW, 1.5 V/ms slew rate; 125 μA per amplifier quiescent current. | Better suited for active filters and higher-frequency sensor interfaces where bandwidth >100 kHz is required. | Select when bandwidth or slew rate outweighs battery life constraints; not drop-in due to 5× higher supply current. |
| OPA333AIDR | Zero-drift architecture: 0.1 μV/°C offset drift vs. 1 μV/°C for LMC6064AIMX/NOPB; 17 μA quiescent current; rail-to-rail I/O. | Preferred for DC-critical applications like precision weight scales where long-term offset stability dominates. | Choose for <1 μV/°C drift requirements; pin-compatible but requires layout review for zero-drift noise performance. |

FAQ
What is the maximum supply voltage for LMC6064AIMX/NOPB?
The absolute maximum supply voltage (V+ − V−) for LMC6064AIMX/NOPB is 16 V. Recommended operating range is 4.5 V to 15 V for single-supply use or ±2.25 V to ±18 V for dual-supply configurations. Exceeding 16 V risks permanent damage per the Absolute Maximum Ratings table in the official datasheet.
Does LMC6064AIMX/NOPB support true rail-to-rail input?
LMC6064AIMX/NOPB supports rail-to-rail *output* swing (within 10 mV of V+ and V−), but its input common-mode range extends to V− and up to (V+) − 2.3 V at 25°C - meaning it accepts signals down to the negative rail (including ground) but not fully to the positive rail. This makes it ideal for single-supply sensor interfaces where the signal originates at or near ground.
Can LMC6064AIMX/NOPB drive capacitive loads directly?
LMC6064AIMX/NOPB is not optimized for direct capacitive load driving. As noted in Section 6.1.3, large capacitive loads reduce phase margin and may cause oscillation. Stable operation requires either a series isolation resistor (e.g., 10–100 Ω) or a pull-up resistor to V+, sized to sink ≥10 μA, depending on required output swing and load capacitance.
What is the input offset voltage drift specification for LMC6064AIMX/NOPB?
The input offset voltage drift for LMC6064AIMX/NOPB is specified as 1 μV/°C maximum over the full operating temperature range of –40°C to +85°C. This low drift ensures minimal calibration drift in precision instrumentation applications such as portable gas analyzers and medical diagnostic equipment.
Is LMC6064AIMX/NOPB pin-compatible with other LMC606x variants?
LMC6064AIMX/NOPB (14-pin SOIC) is not pin-compatible with LMC6061 (8-pin SOIC) or LMC6062 (8-pin SOIC/PDIP). Its 14-pin layout accommodates four independent amplifiers with dedicated inputs and outputs - unlike the dual-channel LMC6062 or single-channel LMC6061 - requiring unique PCB footprint and routing.
