Texas Instruments TLV342ID

Overview

TLV342ID from Texas Instruments is a dual, low-voltage, rail-to-rail output CMOS operational amplifier with shutdown control, designed for precision signal conditioning in space-constrained, battery-powered systems. It delivers 2.3MHz gain bandwidth, 0.9V/μs slew rate, and 70μA/channel supply current at 1.8V, enabling high-fidelity audio preamplification and supply/battery monitoring in portable electronics.

For engineers reviewing the TLV342ID datasheet, TLV342ID pinout, TLV342ID application, or TLV342ID equivalent, key selection criteria include its 1.5V–5.5V single-supply operation, –40°C to 125°C extended temperature range, A-grade 1.25mV max input offset (25°C), and active-low shutdown with 5μs turnon time - all critical for ultra-low-power sensor interfaces and precision analog front-ends.

Technical Context

The TLV342ID implements a PMOS input stage enabling ultra-low 1pA typical input bias current and common-mode input range extending to ground (–0.2V) and within 0.5V of V+, while its CMOS output stage ensures rail-to-rail swing with <25mV low/high-level output voltage drop into 10kΩ at 1.8V. Its dual-channel architecture supports independent signal paths with shared shutdown control.

Shutdown mode reduces total supply current to 10pA per channel (typical), placing outputs in high-impedance state; normal operation resumes within 5μs after SHDN rises above 1.5V (at V+ = 1.8V) or 4.5V (at V+ = 5V). Input offset voltage drift is specified at 1.9μV/°C across –40°C to 125°C.

FAQ

What is the maximum supply voltage rating for TLV342ID?

The absolute maximum supply voltage for TLV342ID is 5.5V. Operation above this level risks permanent damage. The recommended operating range is 1.5V to 5.5V, with full specification compliance guaranteed across this span. At 5V, TLV342ID achieves 2.3MHz GBW and 1V/μs slew rate, while maintaining 1.25mV max input offset for A-grade units at 25°C.

Does TLV342ID support true rail-to-rail input common-mode range?

TLV342ID features a wide input common-mode range from –0.2V to (V+ – 0.5V), which includes ground but does not extend fully to the positive rail. This PMOS-input architecture enables accurate sensing of signals near 0V - critical for single-supply sensor interfaces - while maintaining low input bias current. Full rail-to-rail input would require complementary input stages not present in TLV342ID.

How does the shutdown function behave on TLV342ID?

TLV342ID's SHDN pin (Pin 5 in SOIC) is active-low: driving it below 0.2V places both amplifiers in shutdown mode, reducing total supply current to 10pA typical per channel and forcing outputs into high-impedance state. Release to ≥1.5V (at V+ = 1.8V) or ≥4.5V (at V+ = 5V) restores operation within 5μs. No external pullup is required, but a weak pullup ensures defined state during power-up.

Can TLV342ID drive capacitive loads directly?

TLV342ID is stable driving up to 200pF capacitive loads with 10kΩ series resistance, as verified in typical characteristics (Figure 5-24). For larger loads (e.g., ADC input capacitors >500pF), a 100Ω–500Ω isolation resistor must be placed between TLV342ID output and the load to maintain phase margin >55° and prevent oscillation. This requirement is consistent across 1.8V and 5V supplies.

Is TLV342ID pin-compatible with other dual op-amps in SOIC-8?

TLV342ID uses a standard SOIC-8 pinout (D package) matching industry conventions for dual op-amps: Pin 1 = OUT A, Pin 2 = –IN A, Pin 3 = +IN A, Pin 4 = GND, Pin 5 = SHDN, Pin 6 = +IN B, Pin 7 = –IN B, Pin 8 = V+. While functional compatibility exists with many dual op-amps, the dedicated SHDN pin (Pin 5) is not present in non-shutdown variants - requiring PCB layout modification if substituting parts without shutdown capability.
