Product details
Overview
LMC6064AIM/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 supply current, and 10 fA ultra-low input bias current. It serves as a front-end signal conditioner in battery-powered instrumentation requiring high-impedance sensing and low-drift amplification.
For engineers reviewing the LMC6064AIM/NOPB datasheet, LMC6064AIM/NOPB pinout, LMC6064AIM/NOPB application, or LMC6064AIM/NOPB equivalent, key selection criteria include input bias current stability over temperature, output swing into 100 kΩ loads, common-mode range extending to V−, and guaranteed performance across –40°C to +125°C.
Technical Context
The LMC6064AIM/NOPB employs TI's double-poly silicon-gate CMOS process to achieve ultra-low input bias current (10 fA typ.) and rail-to-rail output stage operation without compromising stability. Its input common-mode range includes V−, enabling true single-supply operation down to 4.5 V.
It features 140 dB open-loop voltage gain, 100 kHz gain-bandwidth product, and 20–35 V/ms slew rate-optimized for precision DC-coupled applications rather than high-speed signal processing. Crosstalk rejection exceeds 155 dB between channels at 100 Hz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 4.5 V to 15 V single supply; supports true ground-referenced input operation |
| Input offset voltage | ±100 µV typical; enables sub-mV DC accuracy in sensor interfaces without trimming |
| Input bias current | ±10 fA typical at 25°C; preserves signal integrity in photodiode, piezoelectric, and high-Z transducer circuits |
| Output swing | Within 10 mV of rails into 100 kΩ load; delivers full dynamic range in low-voltage data acquisition |
| Quiescent current | 16 µA per amplifier; allows four independent channels in <70 µA total system bias current |
| Open-loop gain | 300–4000 V/mV; ensures stable closed-loop gain accuracy even with high feedback impedances |
| CMRR | 75–85 dB (AI grade); maintains accuracy under varying common-mode conditions in bridge-based sensors |
Pinout & Package
LMC6064AIM/NOPB is housed in a 14-pin SOIC (D package) with exposed pad not electrically connected. Pin assignments are validated per TI SNOS631E Rev. MARCH 2025.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT A/B/C/D | Independent buffered outputs per channel; each capable of rail-to-rail sourcing/sinking into ≥100 kΩ |
| 2, 6, 9, 13 | –IN A/B/C/D | Inverting inputs; ultra-high impedance (≥10 TΩ) minimizes loading on high-Z sources |
| 3, 5, 10, 12 | +IN A/B/C/D | Noninverting inputs; common-mode range extends to V−, enabling true single-supply DC coupling |
| 4 | V+ | Positive supply rail; accepts 4.5 V to 15 V; must be ≥2.25 V above V− for dual-supply use |
| 11 | V− | Negative supply rail; referenced to ground in single-supply mode; supports operation down to 0 V |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full-scale analog output within 10 mV of supply rails into 100 kΩ, maximizing ADC utilization in low-voltage systems |
| Ultra-low input bias current | 10 fA typical enables accurate amplification of picoamp-level currents from photodiodes and piezoelectric sensors |
| Input common-mode to V− | Allows direct connection of grounded transducers (e.g., thermocouples, resistive bridges) without level-shifting circuitry |
| 140 dB open-loop gain | Ensures <0.01% gain error with 100 kΩ feedback resistors, critical for precision instrumentation amplifier topologies |
| 155 dB inter-channel crosstalk | Prevents signal coupling between adjacent channels in multi-sensor data loggers and medical ECG front-ends |

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 supply current (550 µA/ch), wider GBW (6.4 MHz), but 1 pA input bias current - 100× higher leakage | Better for AC-coupled, higher-frequency sensor interfaces; unsuitable for pA-level DC current amplification | Select TLV2464IDR only when bandwidth >100 kHz is required and input bias current <100 fA is not critical |
| OPA2333PWR | Zero-drift architecture, 0.02 µV/°C offset drift, but 200 pA input bias current and 17 µA supply current | Superior DC accuracy over temperature; compromised for ultra-high-impedance source interfacing | Choose OPA2333PWR when long-term offset stability dominates over input leakage, e.g., precision voltage references |
Compared with TLV2464IDR and OPA2333PWR, LMC6064AIM/NOPB uniquely balances femtoamp input bias, micropower consumption, and rail-to-rail output in a quad configuration-making it irreplaceable for battery-powered, high-impedance DC signal chains where leakage-induced error must be minimized.

FAQ
What is the maximum supply voltage for LMC6064AIM/NOPB?
The absolute maximum supply voltage (V+ to V−) for LMC6064AIM/NOPB is 16 V. The 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 TI SNOS631E Section 5.1.
Does LMC6064AIM/NOPB support true single-supply operation with input signals at ground?
Yes. LMC6064AIM/NOPB features an input common-mode voltage range that includes V−, allowing its inputs to operate at 0 V when V− is grounded. This enables direct interface with grounded transducers like thermocouples and resistive bridges without level-shifting circuitry.
What is the typical input bias current of LMC6064AIM/NOPB and how does it vary with temperature?
LMC6064AIM/NOPB has a typical input bias current of ±10 fA at +25°C, rising to ±4 pA over the full –40°C to +85°C operating range. This ultra-low leakage is enabled by TI's double-poly CMOS process and makes it suitable for photodiode and piezoelectric sensor interfaces.
Can LMC6064AIM/NOPB drive capacitive loads directly?
LMC6064AIM/NOPB is not optimized for direct capacitive load driving. As shown in TI SNOS631E Figure 6-2 and Section 6.1.3, stable operation with >100 pF loads requires external compensation-such as a series resistor between output and load or a pull-up resistor to V+-to maintain phase margin.
Is LMC6064AIM/NOPB pin-compatible with other LMC606x variants?
No. LMC6064AIM/NOPB uses a 14-pin SOIC package with dedicated pins for four independent channels. LMC6061 (8-pin SOIC) and LMC6062 (8-pin SOIC/PDIP) have different pinouts and channel counts; direct PCB substitution is not possible without layout revision.
