Product details
Overview
LMC6464BIM from Texas Instruments is a quad micropower rail-to-rail input and output CMOS operational amplifier optimized for low-voltage, battery-powered systems. It delivers 20 μA/amplifier supply current, 0.25 mV input offset voltage (typ), 85 dB CMRR at 5V, and rail-to-rail output swing within 10 mV of rails into 25 kΩ - enabling high-accuracy signal conditioning in portable medical sensors and transducer interfaces.
For engineers reviewing the LMC6464BIM datasheet, LMC6464BIM pinout, LMC6464BIM application, or LMC6464BIM equivalent, this page provides verified specifications, package mapping to SOIC-14, real-world design context for ultra-low-IQ instrumentation circuits, and two validated alternative op-amps with documented parameter trade-offs.
Technical Context
The LMC6464BIM employs a CMOS input stage with >10 TΩ input resistance and 150 fA typical input bias current, enabling high-impedance sensor interfacing without significant leakage error. Its rail-to-rail input common-mode range extends 0.2 V beyond both supply rails, and output swing is specified down to 25 kΩ loads - critical for single-supply 3V/5V systems where dynamic range must be maximized.
It features guaranteed operation from 3.0 V to 15.5 V supply, with ensured DC specs at both 3V and 5V. The device achieves 50 kHz gain-bandwidth product and 15 V/ms slew rate at 5V, supporting precision DC and low-frequency AC applications including battery monitoring, ECG front-ends, and photo-detector amplification.

Equivalent & Alternatives
The following parts are listed as comparable options for similar micropower rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Higher supply current (125 μA/amp), lower CMRR (75 dB), but higher GBW (6.4 MHz) | Better for higher-speed sensor interfaces (>100 kHz), less suitable for multi-year battery life | Select TLV2464IDR only when bandwidth >100 kHz is required and power budget allows +55 μA/amp penalty |
| OPA2333AIDR | Zero-drift architecture, 0.02 μV/°C offset drift, but higher IQ (17 μA/amp not guaranteed at 3V) | Superior long-term DC stability in temperature-varying environments; less optimal for fixed-bias transducer apps | Choose OPA2333AIDR for precision weight scales or lab instruments needing <1 μV/°C drift; avoid if strict 20 μA/amp spec is mandatory |
Compared with TLV2464IDR and OPA2333AIDR, the LMC6464BIM uniquely balances ultra-low IQ, rail-to-rail I/O, and guaranteed 3V/5V operation - making it the optimal choice for cost-sensitive, long-life portable instrumentation where sub-100 kHz bandwidth suffices.

FAQ
What is the maximum operating supply voltage for the LMC6464BIM?
The LMC6464BIM supports a supply voltage range of 3.0 V to 15.5 V. Absolute maximum rating is 16 V across V+ and V− pins. Operation above 15.5 V risks parametric degradation or reliability impact, especially under elevated temperature conditions.
Does the LMC6464BIM support true rail-to-rail input common-mode voltage?
Yes - the LMC6464BIM guarantees rail-to-rail input common-mode voltage range, extending 0.2 V beyond both supply rails (e.g., −0.2 V to 5.2 V at VS = 5V). This enables direct interfacing with sensors whose output exceeds the supply, without phase inversion or clipping.
Can the LMC6464BIM drive capacitive loads, and what is its maximum stable value?
The LMC6464BIM can typically drive up to 200 pF capacitively at unity gain with VS = 5V without oscillation. For larger loads (e.g., 300 pF), resistive isolation (e.g., 10–100 Ω series resistor) or feedback compensation (e.g., R1/C1 network per Figure 38) is required to maintain phase margin.
What is the guaranteed input offset voltage specification for LMC6464BIM at 25°C?
The LMC6464BIM has a maximum input offset voltage of 0.5 mV at 25°C (LMC6464BI grade). Typical value is 0.25 mV. This specification is ensured across the full operating temperature range (−40°C to +85°C) per the datasheet's "DC Electrical Characteristics" table.
Is the LMC6464BIM pin-compatible with other members of the LMC646x family?
Yes - the LMC6464BIM (14-pin SOIC) shares identical pinout with all LMC6464 variants (e.g., LMC6464AIM, LMC6464BIN). However, it is not pin-compatible with the dual-channel LMC6462 (8-pin SOIC/PDIP), which uses a different footprint and pin assignment.
