Product details
Overview
LMC6064AIM from Texas Instruments is a quad-channel precision CMOS micropower operational amplifier optimized for single-supply, low-leakage, rail-to-rail output applications. It delivers 100 μV typical offset voltage, 16 μA per amplifier quiescent current, 140 dB open-loop gain, and ultra-low 10 fA input bias current - enabling high-accuracy signal conditioning in battery-powered medical sensors and portable instrumentation.
For engineers reviewing the LMC6064AIM datasheet, LMC6064AIM pinout, LMC6064AIM application, or LMC6064AIM equivalent, key selection criteria include its guaranteed 100 kHz gain-bandwidth product, ±100 μV max offset (AI grade), 14-pin SOIC package compatibility with high-impedance PCB layout requirements, and verified performance across –40°C to +125°C.
Technical Context
The LMC6064AIM employs TI's double-poly silicon-gate CMOS process to achieve true rail-to-rail output swing (within 10 mV of rails at 100 kΩ load) while maintaining input common-mode range extending to V−. Its architecture integrates improved latchup immunity and stable operation with capacitive loads up to 1 nF when compensated with external pull-up resistors or feedback networks.
It supports both single-supply (4.5 V to 15 V) and dual-supply (±2.25 V to ±18 V) operation, with PSRR exceeding 75 dB (positive rail) and 84 dB (negative rail) at 25°C. The device exhibits <1 μV/°C offset drift and >10 TΩ input resistance - critical for photodiode preamplifiers and piezoelectric charge amplifiers where leakage dominates error budgets.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset voltage | ±100 μV typical (AI grade); enables sub-mV DC accuracy in 12-bit+ sensor front-ends without trimming |
| Supply current per amp | 16 μA typical at 25°C; allows four independent channels to operate on <100 μA total supply current |
| Input bias current | 10 fA typical; supports >100 GΩ source impedances in photodiode and transducer interfaces |
| Output swing | Within 10 mV of V+ and V− at 100 kΩ load; delivers full dynamic range in single-supply 5 V systems |
| Gain bandwidth product | 100 kHz; sufficient for DC–10 kHz precision amplification in portable analyzers and medical monitors |
| Open-loop gain | 300–4000 V/mV (300 dB min); ensures <0.01% gain error in unity-gain buffers and instrumentation amps |
| CMRR | 75 dB min (AI grade); rejects common-mode noise in bridge-based transducer circuits |
Pinout & Package
LMC6064AIM is housed in a 14-pin SOIC (D package) with exposed pad thermal enhancement. Pin numbering follows standard TI SOIC top-view convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2, 6, 9, 13 | –IN A/B/C/D | Inverting inputs; matched to respective +IN pins for differential pair stability |
| 3, 5, 10, 12 | +IN A/B/C/D | Noninverting inputs; referenced to guard ring potential in high-Z layouts |
| 4 | V+ | Positive supply rail; accepts 4.5–15 V single supply or highest rail in dual supply |
| 11 | V− | Negative supply rail; extends to ground or negative voltage; input common-mode includes V− |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 10 mV of V+ and V− under 100 kΩ load - preserves full signal headroom in low-voltage battery systems |
| Ultra-low input bias current | 10 fA typical enables direct connection to >100 GΩ sources (e.g., pH electrodes, piezoelectric sensors) |
| High open-loop gain | ≥300 V/mV ensures <0.1% gain error in unity-gain configurations used in precision references and S/H circuits |
| Improved latchup immunity | Withstands 100 mA surge on I/O pins - enhances reliability in noisy industrial environments with ESD events |
| Single-supply operation | Validated from 4.5 V to 15 V with input common-mode range including V− - eliminates need for dual supplies in portable instruments |
Applications
| Portable Medical Sensors | Photodiode Preamp |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision micropower op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMC6044IMX | Higher quiescent current (24 μA/amp), wider supply range (2.7–15.5 V), same 14-pin SOIC package | Better suited for higher-speed applications requiring 200 kHz GBW but sacrifices micropower advantage | Select LMC6044IMX only if >100 kHz bandwidth is required; otherwise LMC6064AIM provides superior power efficiency |
| OPA2333AIDR | Zero-drift architecture, 0.1 μV/°C drift, 17 μA/amp, 360 kHz GBW, 8-pin SOIC (dual only) | Requires two devices for quad functionality; better for DC-critical applications needing sub-μV drift | Choose OPA2333AIDR when long-term DC stability outweighs channel count and power; LMC6064AIM remains optimal for quad, low-IQ needs |
Compared with LMC6064AIM, LMC6044IMX trades 50% higher supply current for doubled bandwidth, while OPA2333AIDR offers zero-drift performance at the cost of dual-only packaging and no native quad option - making LMC6064AIM the only single-package solution meeting <20 μA/amp, quad-channel, and rail-to-rail output requirements.

FAQ
What is the maximum supply voltage rating for LMC6064AIM?
The LMC6064AIM has an absolute maximum supply voltage (V+ to V−) of 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 SNOS631E datasheet. LMC6064AIM must not be operated above this limit even momentarily during power-up sequencing.
Does LMC6064AIM support true rail-to-rail input common-mode range?
LMC6064AIM supports rail-to-rail *output* swing but does not provide rail-to-rail *input* common-mode range. Its input common-mode voltage extends to V− (including ground) but only up to (V+) − 1.9 V at 25°C. This means the upper input limit is ~1.9 V below V+ - sufficient for most single-supply sensor interfaces but requiring level-shifting for signals near V+.
What is the guaranteed input offset voltage specification for LMC6064AIM across temperature?
The LMC6064AIM (AI grade) guarantees ±350 μV maximum input offset voltage at 25°C and ±900 μV maximum over the full –40°C to +85°C operating range. This is explicitly specified in Section 5.7 of the SNOS631E datasheet under "OFFSET VOLTAGE" for LMC606xAI devices. Drift is further limited to ≤1 μV/°C, ensuring predictable performance in thermally varying environments.
Can LMC6064AIM drive capacitive loads directly without external compensation?
LMC6064AIM is not unconditionally stable with direct capacitive loading. Driving >100 pF loads requires external compensation - typically a series resistor (e.g., 10–100 Ω) between output and load, or a pull-up resistor to V+ conducting ≥10 μA. Figure 6-2 and Section 6.1.3 of the datasheet confirm that uncompensated loads >200 pF cause underdamped or oscillatory responses. LMC6064AIM requires careful layout and external components for reliable capacitive load operation.
Is LMC6064AIM pin-compatible with other LMC606x variants?
No, LMC6064AIM is not pin-compatible with LMC6061 or LMC6062. While all share SOIC packaging, LMC6064AIM uses a 14-pin SOIC (D package) with dedicated pins for four independent amplifiers, whereas LMC6061 and LMC6062 use 8-pin SOIC. Pin mapping differs fundamentally: LMC6064AIM has pins 1/7/8/14 as outputs and pins 2/6/9/13 as inverting inputs - a topology unique to the quad variant. Interchangeability requires PCB redesign.
