Product details
Overview
LMC6064IMX/NOPB from Texas Instruments is a quad-channel precision CMOS operational amplifier optimized for micropower, single-supply operation with rail-to-rail output swing, 100 µV typical input offset voltage, 16 µA per amplifier quiescent current, and 10 fA ultra-low input bias current - enabling high-accuracy signal conditioning in battery-powered instrumentation and sensor front-ends.
For engineers reviewing the LMC6064IMX/NOPB datasheet, LMC6064IMX/NOPB pinout, LMC6064IMX/NOPB application, or LMC6064IMX/NOPB equivalent, key selection criteria include input bias current stability over temperature, output swing within 10 mV of rails at 100 kΩ load, common-mode input range extending to V−, and guaranteed performance across –40°C to +125°C.
Technical Context
The LMC6064IMX/NOPB employs TI's double-poly silicon-gate CMOS process to achieve ultra-low input bias current (10 fA typ.) and high input resistance (>10 TΩ), supporting precision transducer interfacing without guard-ring layout dependency. Its internal compensation enables stable operation with capacitive loads up to 1 nF when paired with appropriate series resistance.
It delivers rail-to-rail output swing (e.g., 0.010 V to 4.995 V on 5 V supply, 100 kΩ load) while maintaining 140 dB open-loop gain and 75–85 dB CMRR across –40°C to +85°C, making it suitable for high-impedance, low-power analog signal chains where DC accuracy and thermal drift are critical.
Key Specifications

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 |
|---|---|---|---|
| TLV2464IDR | Higher quiescent current (550 µA/ch), lower input impedance (10⁶ Ω), 2.5 mV offset - trades power for speed (6 MHz GBW) | Suitable for higher-bandwidth sensor interfaces but unsuitable for fA-level photodiode or piezo charge amplification | Select TLV2464IDR only when >100 kHz signal bandwidth is required and input bias current >1 pA is acceptable |
| OPA2333PWR | Zero-drift architecture, 0.1 µV offset, 17 µA/ch, but 200 pA input bias current - superior DC accuracy, inferior high-Z interface capability | Better for precision reference buffers and low-drift integrators; less ideal for transducer preamps with >1 GΩ source impedance | Choose OPA2333PWR when sub-µV offset and near-zero drift dominate requirements over femtoampere input bias |
Compared with TLV2464IDR and OPA2333PWR, LMC6064IMX/NOPB uniquely balances femtoampere input bias, rail-to-rail output, and micropower operation - making it irreplaceable for battery-powered, ultra-high-impedance analog front-ends where leakage and supply current are primary constraints.

FAQ
What is the maximum operating temperature range for LMC6064IMX/NOPB?
The LMC6064IMX/NOPB is specified for operation from –40°C to +125°C ambient temperature. Electrical characteristics including input offset voltage drift (1 µV/°C), CMRR (≥72 dB), and output swing are guaranteed across this full industrial temperature range - enabling use in automotive under-hood and industrial control cabinet environments without derating.
Does LMC6064IMX/NOPB support true single-supply operation with input signals at ground?
Yes, LMC6064IMX/NOPB supports true single-supply operation with its input common-mode voltage range extending to V− (ground in single-supply configuration). This allows direct interfacing with grounded sensors such as strain gauges, thermistors, and pH electrodes without external biasing networks - preserving signal integrity and minimizing component count.
What is the typical output drive capability of LMC6064IMX/NOPB at 5 V supply?
At 5 V supply and 100 kΩ load, LMC6064IMX/NOPB delivers output swing from 0.010 V to 4.995 V - within 10 mV of both rails. It sources/sinks up to 22 mA short-circuit current (typ.), enabling direct driving of moderate-impedance loads like ADC reference buffers and LED indicators without external transistors.
How does LMC6064IMX/NOPB handle capacitive loads in precision applications?
LMC6064IMX/NOPB maintains stability with capacitive loads up to 1 nF when used with recommended compensation techniques - including series resistance (e.g., 90 kΩ pull-up to V+) or feedback capacitor placement. Its internal compensation and low output impedance prevent oscillation in sample-and-hold and filter circuits where stray capacitance exceeds 100 pF.
Is LMC6064IMX/NOPB pin-compatible with other LMC606x variants?
No - LMC6064IMX/NOPB uses a 14-pin SOIC package, while LMC6061 (8-pin SOIC) and LMC6062 (8-pin SOIC/PDIP) have different pin counts and layouts. Pin functions are not interchangeable; PCB redesign is required when migrating between channel counts. The LMC6064IMX/NOPB pinout is fixed per Figure 4-3 in the official datasheet SNOS631E.
