Product details
Overview
LMC6064IM/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 LMC6064IM/NOPB datasheet, LMC6064IM/NOPB pinout, LMC6064IM/NOPB application, or LMC6064IM/NOPB equivalent, key selection criteria include verified rail-to-rail output drive into 100 kΩ loads, guaranteed 16 µA per amplifier quiescent current, ultra-high input impedance (>10 TΩ), and SOIC-14 package compatibility with space-constrained analog signal chains.
Technical Context
The LMC6064IM/NOPB employs TI's double-poly silicon-gate CMOS process to achieve true rail-to-rail output swing while maintaining stability across capacitive loads up to 1 nF when compensated with external resistors. Its input stage includes ground-referenced common-mode range and latchup immunity rated for ±100 mA surge current on I/O pins.
It features a novel internal compensation topology that supports stable unity-gain operation and enables use in precision integrators, sample-and-hold circuits, and instrumentation amplifiers without external phase compensation - unlike conventional micropower op amps requiring careful layout guard rings for sub-picoampere leakage control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 15 V single supply; enables direct interfacing with 5 V and 12 V systems without level-shifting. |
| Input Bias Current | 10 fA typical; ensures <100 fA total input leakage in photodiode preamplifier configurations with guarded PCB layout. |
| Input Offset Voltage | ±100 µV max (AI grade); supports 16-bit DAC buffer accuracy without trimming in portable medical instruments. |
| Quiescent Current | 16 µA per amplifier; allows four independent channels to operate continuously for >1 year on a single CR2032 coin cell. |
| Open-Loop Gain | 300 V/mV min; provides ≥90 dB loop gain at 100 kΩ load for stable closed-loop gain accuracy in transducer amplifiers. |
| Output Swing | Within 10 mV of V+ and V− at 100 kΩ; delivers full dynamic range in single-supply 0–5 V data acquisition systems. |
| Gain Bandwidth Product | 100 kHz; sufficient for DC–10 kHz sensor signal conditioning including piezoelectric charge amplification. |
Pinout & Package
LMC6064IM/NOPB is housed in a 14-pin SOIC (D package) with exposed pad not present; thermal resistance RθJA = 126.0°C/W enables operation up to +125°C ambient with minimal derating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT A/B/C/D | Independent buffered outputs; each capable of sourcing/sinking ≥16 mA into 100 kΩ loads near rails. |

| 3, 5, 10, 12 | +IN A/B/C/D | Noninverting inputs; common-mode range extends to V− (ground); critical for single-supply sensor biasing. |
| 4 | V+ | Positive supply rail; must be decoupled with ≥0.1 µF ceramic capacitor placed within 5 mm of pin. |
| 11 | V− | Negative supply rail; serves as reference for all inputs and outputs in single-supply mode (0 V). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full-scale output within 10 mV of V+ and V− under 100 kΩ load - eliminates need for dual supplies in portable analyzers. |

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/channel), wider GBW (6.4 MHz), but 1 pA input bias current - 100× higher than LMC6064IM/NOPB. | Suitable for higher-speed sensor interfaces where power budget allows; not viable for femtoampere current measurement. | Select TLV2464IDR only when bandwidth >100 kHz is required and input leakage <100 fA is not critical. |
| OPA333AIDR | Zero-drift architecture; 2 µV max offset, 0.02 µV/°C drift, but 200 pA input bias current and 36 µA quiescent current. | Better DC accuracy for precision references; unsuitable for photodiode or piezoelectric charge integration due to input leakage. | Choose OPA333AIDR for ultra-low-offset DC-coupled buffers where input current is not limiting; avoid for high-Z sensor nodes. |
Compared with TLV2464IDR and OPA333AIDR, the LMC6064IM/NOPB uniquely balances femtoampere input bias, micropower consumption, and rail-to-rail output - making it irreplaceable in battery-operated, high-impedance analog front-ends where leakage and supply current dominate design constraints.

FAQ
What is the maximum supply voltage for LMC6064IM/NOPB?
The absolute maximum supply voltage for LMC6064IM/NOPB is 16 V, but the recommended operating range is 4.5 V to 15 V for reliable performance. Operation above 15 V risks exceeding junction temperature limits and may degrade long-term reliability, especially under high-output-current conditions. The LMC6064IM/NOPB datasheet specifies that connecting the output directly to V+ when V+ exceeds 13 V can adversely affect device reliability.
Does LMC6064IM/NOPB support true single-supply operation with input referenced to ground?
Yes, LMC6064IM/NOPB supports true single-supply operation with its input common-mode voltage range extending to V− (0 V). This allows direct interfacing with grounded sensors such as thermocouples, strain gauges, and bridge transducers without level-shifting circuitry - a key enabler for compact, low-component-count analog front-ends in portable instrumentation.
Can LMC6064IM/NOPB drive capacitive loads without oscillation?
LMC6064IM/NOPB is not unconditionally stable with direct capacitive loading, but it can reliably drive up to 1 nF when compensated using TI-recommended techniques: adding a pull-up resistor to V+ (≥10 µA current) or inserting an RC network (e.g., 90 kΩ + 20 pF) in the feedback path. These methods restore phase margin lost due to the pole formed by output impedance and load capacitance.
What is the typical input offset voltage drift of LMC6064IM/NOPB over temperature?
The LMC6064IM/NOPB exhibits a typical input offset voltage drift of 1 µV/°C over the –40°C to +85°C range. This low drift, combined with its ±100 µV max initial offset, ensures minimal baseline shift in precision DC-coupled applications such as medical sensor amplifiers and portable analytical instruments operating across wide ambient temperatures.
Is LMC6064IM/NOPB pin-compatible with other quad op amps in SOIC-14 packages?
No, LMC6064IM/NOPB has a unique pinout optimized for independent channel routing and low-leakage layout - differing from industry-standard quad op amps like LM324 or TLV2464. Its V− pin is located at pin 11 and V+ at pin 4, with noninverting inputs on odd-numbered pins (3,5,10,12) and inverting inputs on even-numbered pins (2,6,9,13). PCB redesign is required for substitution.
