Texas Instruments LMV342ID

Overview

LMV342ID from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier with shutdown capability, designed for low-voltage (2.7V–5.5V) battery-powered systems. It delivers 1MHz gain bandwidth, 1V/μs slew rate, 0.25mV typical input offset voltage, and ultra-low 1pA typical input bias current - enabling precision signal conditioning in space-constrained portable audio and sensor interfaces.

For engineers reviewing the LMV342ID datasheet, LMV342ID pinout, LMV342ID application, or LMV342ID equivalent, this page provides verified package mapping (SOIC-8), confirmed dual-channel functional behavior, shutdown timing (5μs turn-on), rail-to-rail output swing (≤30mV from rails at 10kΩ), and real-world use cases in battery monitoring and audio preamplification - all extracted from TI's SLOS447J production datasheet (Rev. JUNE 2025).

Technical Context

The LMV342ID implements a PMOS input stage enabling rail-to-rail common-mode input range down to ground and up to V+ – 1V, paired with a CMOS output stage delivering true rail-to-rail swing (≤30mV from supply rails under 10kΩ load). Its dual-channel architecture shares a single shutdown control line (active-low SHDN on Pin 5), allowing independent channel disablement while maintaining high-impedance output states.

Operating across –40°C to +125°C, the device supports stable performance at 2.7V and 5V supplies, with 60dB minimum CMRR over full temperature range and 65dB minimum PSRR - making it suitable for noisy industrial sensor front-ends and precision supply-current monitoring where input bias current <1pA prevents signal corruption in high-impedance source networks.

Key Specifications

Pinout & Package

LMV342ID is housed in an 8-pin SOIC (D) package measuring 4.90mm × 3.91mm, rated for surface-mount assembly and industrial temperature operation (–40°C to +125°C).

FAQ

What is the maximum supply voltage for LMV342ID?

The absolute maximum supply voltage for LMV342ID is 5.5V. Operation above this level risks permanent damage. The recommended operating range is 2.5V to 5.5V, with full specification compliance at 2.7V and 5V. This makes LMV342ID compatible with standard 3.3V and 5V rails, as well as single-cell Li-ion (up to 4.2V) and regulated 2.7V systems - all confirmed in Section 5.1 and 5.3 of the SLOS447J datasheet.

Does LMV342ID have a shutdown pin, and how does it function?

Yes, LMV342ID includes an active-low shutdown pin (SHDN) on Pin 5. When pulled low (≤0.2V), the device enters shutdown mode, reducing total supply current to 33nA (typical at 5V) and placing both outputs in high-impedance state. Turn-on time from shutdown is 5μs (typical). This functionality is explicitly defined in Sections 4.2, 5.7, 5.8, and 6.3.3 of the LMV342ID datasheet - distinguishing it from non-shutdown variants like LMV358.

What is the input common-mode voltage range for LMV342ID?

The input common-mode voltage range for LMV342ID extends from –0.2V to (V+ – 1V) - meaning it includes ground (0V) and supports inputs up to 1V below the positive supply rail. At 2.7V supply, this spans –0.2V to 1.7V; at 5V, it spans –0.2V to 4V. This is verified in Tables 5.5 and 5.6 (VICR parameter) and Section 6.3.1 (PMOS input stage description) of the official TI datasheet.

Can LMV342ID drive a 600Ω load in audio applications?

LMV342ID can source up to 85mA and sink up to 50mA (at 5V, 25°C), making it capable of driving 600Ω loads with ≤1VPP output swing. However, THD+N rises to 0.012% at 1kHz under those conditions (Section 5.6), and output swing degrades to ~2.4VPP due to rail limitations. For optimal audio fidelity, use 10kΩ+ loads - where LMV342ID delivers 39nV/√Hz noise and 0.012% THD+N - as validated in Figure 5-19 and Table 5.6.

Is LMV342ID pin-compatible with other dual op-amps in SOIC-8 packages?

No, LMV342ID is not pin-compatible with generic dual op-amps like LM358 or TL072. Its SOIC-8 pinout (1OUT, 1IN–, 1IN+, GND, 2IN+, 2IN–, 2OUT, V+) is unique to the LMV34x family and includes dedicated SHDN functionality absent in legacy parts. Substituting requires PCB redesign. Confirmed via direct comparison of Figures 4-2 (LMV342) and Figure 4-4 (LM358) in TI's SLOS447J and SNOSBT7 datasheets.
