Texas Instruments LMC6062IN/NOPB

Overview

LMC6062IN/NOPB from Texas Instruments is a dual-channel precision CMOS micropower operational amplifier optimized for battery-powered instrumentation and high-impedance sensor interfaces. It delivers 100 µV typical input offset voltage, 16 µA per amplifier quiescent current, rail-to-rail output swing within 10 mV of supply rails (at 100 kΩ load), ultra-low 10 fA input bias current, and 140 dB open-loop voltage gain - enabling accurate signal conditioning in portable medical devices and photodiode preamplifiers.

For engineers reviewing the LMC6062IN/NOPB datasheet, LMC6062IN/NOPB pinout, LMC6062IN/NOPB application, or LMC6062IN/NOPB equivalent, key selection criteria include verified micropower operation down to 4.5 V single supply, guaranteed input common-mode range extending to V−, and confirmed dual-channel SOIC-8 pin compatibility with documented thermal derating guidance for industrial temperature range (–40°C to +125°C).

Technical Context

The LMC6062IN/NOPB 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 high-impedance feedback networks. Its architecture supports true single-supply operation with input common-mode voltage including V−, eliminating need for level-shifting in ground-referenced transducer interfaces.

Internal compensation enables stable unity-gain operation with >100 kHz gain-bandwidth product and 20–35 V/ms slew rate, while crosstalk rejection exceeds 155 dB between channels - critical for dual-path instrumentation amplifier topologies and low-leakage sample-and-hold circuits where channel isolation directly impacts measurement integrity.

FAQ

What is the maximum supply voltage for LMC6062IN/NOPB?

The absolute maximum supply voltage for LMC6062IN/NOPB is 16 V, but the recommended operating range is 4.5 V to 15 V. Operation above 13 V requires caution: connecting the output directly to V+ under those conditions may adversely affect long-term reliability, as specified in the Absolute Maximum Ratings table of the SNOS631E datasheet. For 15 V operation, ensure output loading and thermal management comply with θJA = 115 °C/W for the PDIP package.

Does LMC6062IN/NOPB support true single-supply operation with input signals at ground?

Yes, LMC6062IN/NOPB supports true single-supply operation with input common-mode voltage extending to V− (i.e., ground when V− = 0 V). This is explicitly confirmed in the device description and electrical characteristics tables, enabling direct interfacing with grounded transducers like strain gauges and thermocouples without level-shifting circuitry - a key differentiator versus many older CMOS op amps.

What is the typical input bias current of LMC6062IN/NOPB, and why does it matter?

The typical input bias current of LMC6062IN/NOPB is 10 fA at +25°C, with ≤4 pA over –40°C to +85°C. This ultra-low value is critical when interfacing with high-impedance sources such as photodiodes, piezoelectric sensors, and pH electrodes - where even picoampere-level leakage would introduce significant offset, drift, or signal attenuation. It directly enables >10 TΩ effective source impedance handling.

Can LMC6062IN/NOPB drive capacitive loads, and what layout guidance applies?

LMC6062IN/NOPB can drive moderate capacitive loads with proper compensation: Figure 6-2 in SNOS631E shows stable operation with 1 nF via a 90 kΩ/10 kΩ resistive divider network. For high-impedance nodes, TI recommends guard rings tied to input potential and air-wiring of input pins to minimize surface leakage - techniques validated in Section 6.3.1.1 to preserve the device's 10 fA bias current specification.

Is LMC6062IN/NOPB pin-compatible with other LMC606x variants?

LMC6062IN/NOPB shares identical pinout with LMC6062IM/NOPB (SOIC-8) but differs from LMC6061 and LMC6064 due to channel count: the LMC6061 uses pins 1–8 in SOIC-8 with single-channel mapping, while LMC6064 uses 14-pin SOIC with four independent channels. No cross-voltage or cross-channel pin compatibility exists outside the LMC6062 family members; substitution requires matching channel count and package type.
