Product details
Overview
LMC6064IN/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 medical instrumentation and portable analytical sensors.
For engineers reviewing the LMC6064IN/NOPB datasheet, LMC6064IN/NOPB pinout, LMC6064IN/NOPB application, or LMC6064IN/NOPB equivalent, key selection criteria include verified input bias current ≤10 fA at 25°C, guaranteed rail-to-rail output swing within 10 mV of supply rails under 100 kΩ load, and confirmed SOIC-14 package compatibility with standard surface-mount assembly processes.
Technical Context
The LMC6064IN/NOPB employs TI's double-poly silicon-gate CMOS process to achieve ultra-low input bias current while maintaining stable unity-gain operation across 4.5 V to 15 V single-supply or ±2.25 V to ±18 V dual-supply configurations. Its input common-mode range includes the negative rail (V−), supporting true ground-referenced sensing.
Internal compensation ensures stability with capacitive loads up to 1 nF when used with appropriate series resistance, and crosstalk between channels is suppressed to 155 dB at 100 Hz - critical for multi-channel sensor front-ends where channel isolation must exceed 140 dB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input offset voltage | ±100 µV typical - enables sub-mV DC accuracy in precision transducer amplifiers without trimming |
| Quiescent current per amplifier | 16 µA at 25°C - supports >1-year battery life in continuous 3.3 V/AA-cell portable instruments |
| Input bias current | 10 fA typical - preserves signal integrity in photodiode and piezoelectric charge amplifiers |
| Output swing | Within 10 mV of V+ and V− at 100 kΩ load - delivers full dynamic range in single-supply 5 V systems |
| Open-loop gain | 300–4000 V/mV - ensures ≥80 dB closed-loop gain accuracy for 100× instrumentation amplifier designs |
| Gain bandwidth product | 100 kHz - suitable for low-frequency sensor signals (<10 kHz) with minimal phase error |
| Crosstalk | 155 dB at 100 Hz - prevents inter-channel coupling in 4-channel ECG or multi-sensor data acquisition |
Pinout & Package
LMC6064IN/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 standard PCB copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT A/B/C/D | Amplifier output terminals - each capable of sourcing/sinking ≥16 mA into 100 kΩ load |
| 2, 6, 9, 13 | –IN A/B/C/D | Inverting inputs - high-impedance nodes requiring guard ring layout to preserve 10 fA bias current spec |
| 3, 5, 10, 12 | +IN A/B/C/D | Noninverting inputs - accept common-mode voltages down to V− (ground in single-supply) |
| 4 | V+ | Positive supply terminal - supports 4.5 V to 15 V single-supply or highest rail in dual-supply |
| 11 | V− | Negative supply terminal - lowest rail; input common-mode extends to this pin |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output stage | Delivers full 0 V to V+ swing with <10 mV headroom at 100 kΩ - eliminates need for level-shifting in 3.3 V/5 V microcontroller interfaces |
| Ultra-low input bias current | 10 fA typical - reduces input leakage error to <0.1 µV in 100 MΩ feedback networks used with photodiodes |
| High open-loop gain | ≥300 V/mV minimum - maintains gain accuracy better than 0.1% in unity-gain buffers and precision integrators |
| Input common-mode range includes V− | Enables direct connection of grounded sensors (e.g., thermocouples, pH electrodes) without level-shifting circuitry |
| 155 dB channel crosstalk suppression | Prevents signal bleed between adjacent amplifier channels in 4-channel bio-signal acquisition systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMC6064IMX/NOPB | Same electrical specs; tape-and-reel packaging instead of tube - identical SOIC-14 footprint and pinout | No functional difference; selected for automated SMT line compatibility | Choose LMC6064IMX/NOPB for high-volume production requiring reel-fed placement |
| OPA2182IDR | Lower offset (±4 µV), higher IQ (220 µA), 10 MHz GBW - not micropower but higher precision | Suitable only where power budget allows >13× higher current draw for improved DC accuracy | Select OPA2182IDR only when sub-µV offset and 120 dB CMRR outweigh battery-life constraints |
Compared with LMC6064IN/NOPB, LMC6064IMX/NOPB offers identical performance in tape-and-reel format for volume manufacturing, while OPA2182IDR trades 13× higher supply current for 25× lower offset voltage - making it viable only in line-powered or high-duty-cycle applications where micropower is secondary to absolute DC precision.

FAQ
What is the maximum supply voltage for LMC6064IN/NOPB?
The LMC6064IN/NOPB supports a maximum supply voltage of 16 V across V+ and V− pins. Absolute maximum rating is 16 V for VS = (V+) − (V−); operation beyond this risks permanent damage. 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 - with LMC6064IN/NOPB validated for reliable operation at 15 V single-supply per TI SNOS631E datasheet Section 5.1.
Does LMC6064IN/NOPB support true rail-to-rail input?
LMC6064IN/NOPB does not support rail-to-rail input common-mode range - its input common-mode voltage extends to the negative rail (V−) but only to (V+) − 1.9 V at 25°C. However, it does provide rail-to-rail output swing within 10 mV of both supply rails under 100 kΩ load, as confirmed in Section 5.7 of the LMC6064IN/NOPB datasheet.
What is the guaranteed input bias current specification for LMC6064IN/NOPB over temperature?
LMC6064IN/NOPB guarantees input bias current ≤ ±4 pA over the full –40°C to +85°C operating range, with typical value of 10 fA at 25°C. This is explicitly specified in Table 5.7 of the official datasheet under "INPUT BIAS CURRENT" test conditions, ensuring predictable leakage behavior in high-impedance sensor interfaces across industrial temperature extremes.
Can LMC6064IN/NOPB drive capacitive loads directly?
LMC6064IN/NOPB is not optimized for direct capacitive load driving; stability degrades with loads >100 pF. Section 6.1.3 of the datasheet recommends adding a series resistor (e.g., 20 Ω to 100 Ω) between the output and capacitive load, or using a pullup resistor to V+ to maintain phase margin - verified in Figure 6-2 and Figure 6-3 for loads up to 1 nF when compensated.
Is LMC6064IN/NOPB pin-compatible with other LMC606x variants?
LMC6064IN/NOPB is not pin-compatible with LMC6061 or LMC6062 due to differing channel counts and pinouts: LMC6064IN/NOPB uses 14-pin SOIC with dedicated pins for four independent amplifiers, while LMC6062 uses 8-pin SOIC/PDIP and LMC6061 uses 8-pin SOIC. Pin mapping, supply pin locations (V+ at pin 4, V− at pin 11), and channel routing are unique to the quad variant - confirmed in Figures 4-1 through 4-3 of SNOS631E.
