Texas Instruments LMC6062IMX

Overview

LMC6062IMX from Texas Instruments is a dual-channel precision CMOS micropower operational amplifier optimized for battery-powered instrumentation and low-leakage signal conditioning. It delivers 100 µV typical input offset voltage, 16 µA per amplifier quiescent current, 140 dB open-loop gain, rail-to-rail output swing within 10 mV of supply rails (at 100 kΩ load), and 10 fA ultra-low input bias current - enabling high-accuracy DC amplification in portable medical sensors and photodiode preamplifiers.

For engineers reviewing the LMC6062IMX datasheet, LMC6062IMX pinout, LMC6062IMX application, or LMC6062IMX equivalent, key selection criteria include its dual SOIC-8 package, guaranteed operation from 4.5 V to 15 V single supply (or ±2.25 V to ±18 V dual supply), –40°C to +125°C temperature range, and compatibility with high-impedance transducer interfaces requiring sub-picoampere bias current and <1 µV/°C offset drift.

Technical Context

The LMC6062IMX employs TI's double-poly silicon-gate CMOS process to achieve ultra-low input bias current and rail-to-rail output drive while maintaining stability across capacitive loads and wide supply ranges. Its architecture supports true single-supply operation with input common-mode range extending to V−, enabling ground-referenced sensor interfacing without level-shifting.

Internal compensation ensures stable unity-gain operation with >60° phase margin into 100 pF loads when used with appropriate pull-up resistors or feedback networks. The device features improved latchup immunity (100 mA I/O surge tolerance) and integrates no internal ESD diodes to ground or supply rails - preserving input integrity in high-impedance measurement paths.

FAQ

What is the maximum supply voltage for LMC6062IMX?

The LMC6062IMX has an absolute maximum supply voltage (V_S = V₊ − V₋) of 16 V. Operation beyond this rating 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. Exceeding 13 V on V₊ while sinking output current may reduce reliability per TI's datasheet caution.

Does LMC6062IMX support true rail-to-rail input common-mode range?

The LMC6062IMX supports rail-to-rail output swing but does not feature rail-to-rail input common-mode range. Its input common-mode voltage extends to V₋ (including ground) but only up to (V₊ − 1.9 V) at 25°C - meaning it cannot accept signals within ~2 V of the positive rail. This limitation is explicitly specified in the Electrical Characteristics table under V_CM (To positive rail).

Can LMC6062IMX drive capacitive loads directly?

The LMC6062IMX is not unity-gain stable into pure capacitive loads. Direct connection to >100 pF loads causes phase-margin degradation and potential oscillation. Stable operation requires either a series isolation resistor (e.g., 10–100 Ω) between output and capacitance, a pull-up resistor to V₊ (≥10 µA current), or feedback network compensation - as detailed in Section 6.1.3 of the SNOS631E datasheet.

What is the guaranteed input offset voltage specification for LMC6062IMX over temperature?

For the LMC6062IMX industrial-grade variant (suffix 'I'), the input offset voltage is guaranteed at ±800 µV over –40°C to +85°C, and ±1300 µV over the full –40°C to +125°C range. The 'AI' grade offers tighter initial offset (±350 µV) and ±900 µV over –40°C to +85°C. These values are specified in Table 5.7 of the official datasheet and apply to the exact LMC6062IMX ordering option.

Is LMC6062IMX pin-compatible with other LMC606x variants?

LMC6062IMX (dual-channel, SOIC-8) shares identical pinout with LMC6061 (single, SOIC-8) and LMC6062 in PDIP-8 (P package), but is not pin-compatible with LMC6064 (quad, SOIC-14). Channel count and package footprint differences prevent direct substitution without PCB redesign. The SOIC-8 pin mapping is standardized across LMC6061 and LMC6062 D-package variants per Figure 4-1 and 4-2 in SNOS631E.
