Product details
Overview
LMC6064IMX from Texas Instruments is a quad-channel precision CMOS operational amplifier optimized for micropower, single-supply operation with rail-to-rail output swing, ultra-low input bias current (10 fA), 100 µV typical offset voltage, and 16 µA per amplifier supply current - ideal for battery-powered instrumentation and sensor signal conditioning.
For engineers reviewing the LMC6064IMX datasheet, LMC6064IMX pinout, LMC6064IMX application, or LMC6064IMX 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 employs TI's double-poly silicon-gate CMOS process to achieve ultra-high input impedance (>10 TΩ) and latchup immunity. Its architecture supports true single-supply operation with input common-mode range including V− and rail-to-rail output swing under 100 kΩ loads.
It delivers 140 dB open-loop voltage gain and 100 kHz gain-bandwidth product while maintaining 20–35 V/ms slew rate and <0.01% THD at 1 kHz - enabling precision DC-coupled amplification and low-distortion signal buffering without external level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset voltage | ±100 µV typical; enables sub-mV DC error in high-gain transducer interfaces without trimming |
| Input bias current | 10 fA typical; preserves signal integrity in photodiode, piezoelectric, and high-impedance sensor front-ends |
| Supply current per amp | 16 µA typical; supports multi-channel, always-on sensing in portable medical and analytical instruments |
| Output swing | Within 10 mV of V+ and V− at 100 kΩ load; maximizes dynamic range in 3.3 V or 5 V single-supply systems |
| Input common-mode range | Includes V− (ground); eliminates need for negative supply in single-ended sensor interfaces |
| Open-loop gain | 140 dB typical; ensures stable closed-loop gain accuracy >99.9% for gains up to 1000 |
| Gain-bandwidth product | 100 kHz; sufficient for precision DC–10 kHz signal conditioning in portable instrumentation |
Pinout & Package
LMC6064IMX 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 without forced airflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT A–D | Amplifier output channels; each drives ≥100 kΩ load to within 10 mV of supply rails |
| 2, 6, 9, 13 | –IN A–D | Inverting inputs; support high-impedance feedback networks without bias current error |
| 3, 5, 10, 12 | +IN A–D | Noninverting inputs; accept common-mode voltages down to V− (0 V in single-supply) |
| 4 | V+ | Positive supply pin; operates from 4.5 V to 15 V (single) or ±2.25 V to ±18 V (dual) |
| 11 | V− | Negative supply pin; referenced to ground in single-supply mode; enables true ground-sensing |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full-scale output at 100 kΩ load without headroom loss - critical for low-voltage ADC interfacing |
| Ultra-low input bias current | 10 fA typical ensures <0.1 mV error from 1 GΩ source impedance - essential for photodiode preamps |
| Single-supply capable architecture | Input common-mode includes V− and output swings to V−, eliminating need for dual supplies in portable designs |
| High CMRR and PSRR | 85 dB typical CMRR and PSRR suppress noise from shared supply rails and common-mode interference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Higher quiescent current (550 µA/amp), wider GBW (6.4 MHz), no guaranteed 10 fA IB | Better for AC-coupled, higher-speed sensor interfaces; unsuitable for femtoamp-level photodiode or piezo charge integration | Select when speed >100 kHz required and supply current budget allows >30× increase over LMC6064IMX |
| OPA2182IDGKR | Zero-drift architecture, 0.02 µV/°C drift, 550 µA/amp, 5.7 MHz GBW, no rail-to-rail output | Superior DC precision for lab-grade instrumentation; requires dual supply or level-shifting for single-supply use | Choose for sub-µV offset stability over temperature where micropower is secondary to absolute accuracy |
Compared with TLV2464IDR and OPA2182IDGKR, LMC6064IMX uniquely balances femtoamp input bias, rail-to-rail output, and micropower in a single quad package - making it irreplaceable in battery-powered, high-impedance analog front-ends where leakage and supply constraints dominate.

FAQ
What is the maximum operating temperature range for LMC6064IMX?
The LMC6064IMX is specified for operation from –40°C to +125°C ambient temperature. This extended range is validated per TI's SNOS631E datasheet, with electrical characteristics guaranteed across this full interval - supporting deployment in automotive cabin modules, industrial field transmitters, and outdoor environmental monitors where thermal extremes occur.
Does LMC6064IMX support true single-supply operation with input down to ground?
Yes, LMC6064IMX supports true single-supply operation: its input common-mode voltage range explicitly includes V−, meaning it accepts signals down to ground (0 V) when V− is tied to GND. This eliminates level-shifting circuitry in sensor interfaces like bridge transducers or pH electrodes - a key design advantage confirmed in Section 3 and Table 4-3 of the datasheet.
What is the typical output swing capability of LMC6064IMX at 5 V supply?
At V+ = 5 V and V− = 0 V with a 100 kΩ load, LMC6064IMX delivers typical output swing of 4.990 V (positive rail) and 0.005 V (negative rail), i.e., within 10 mV of both supply rails. This rail-to-rail performance is measured per Section 5.7 and enables full utilization of 3.3 V or 5 V ADC reference ranges without signal clipping.
Can LMC6064IMX drive capacitive loads directly?
LMC6064IMX is not optimized for direct capacitive loading: its stability degrades with >100 pF loads unless compensated. Section 6.1.3 recommends adding a series resistor (e.g., 10–100 Ω) or pull-up resistor to V+ to maintain phase margin. For direct 1 nF+ loads, external isolation or active compensation (e.g., Figure 6-2) is required - verified in Figures 5-21/5-22 of the datasheet.
Is LMC6064IMX pin-compatible with other LMC606x variants?
No, LMC6064IMX is not pin-compatible with LMC6061 or LMC6062: it uses a 14-pin SOIC package (D), whereas LMC6061/LMC6062 use 8-pin SOIC (D) or PDIP (P). Pin count, layout, and terminal mapping differ fundamentally - confirmed in Figures 4-1 through 4-3 and Table 4-3. PCB redesign is required for substitution.
