Texas Instruments TLV341AIDCKTG4

Overview

TLV341AIDCKTG4 from Texas Instruments is a single-channel, low-voltage, rail-to-rail output CMOS operational amplifier with active-low 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 1.25mV maximum input offset voltage (25°C), enabling high-accuracy DC-coupled amplification in portable audio preamplifiers and supply current monitoring circuits.

For engineers reviewing the TLV341AIDCKTG4 datasheet, TLV341AIDCKTG4 pinout, TLV341AIDCKTG4 application, or TLV341AIDCKTG4 equivalent, key selection criteria include its 1.5V–5.5V single-supply operation, 70μA/channel quiescent current, 10pA typical shutdown current, rail-to-rail output swing within 7mV of rails (at 10kΩ load), and SC70-6 package footprint compatibility with ultra-low-power sensor interfaces and battery voltage monitors.

Technical Context

The TLV341AIDCKTG4 employs a PMOS input stage to achieve 1pA typical input bias current and ground-inclusive common-mode range (–0.2V to V+ – 0.5V), supporting direct coupling in single-supply systems. Its CMOS output stage enables rail-to-rail swing with <25mV headroom at 10kΩ load across temperature.

Shutdown functionality is implemented via an active-low SHDN pin that reduces supply current to 10pA per channel while placing the output in high-impedance state; turn-on time from shutdown is 5μs typical, ensuring rapid reactivation in duty-cycled applications without output glitches.

FAQ

What is the maximum supply voltage rating for TLV341AIDCKTG4?

The absolute maximum supply voltage for TLV341AIDCKTG4 is 5.5V. Operation above this level risks permanent damage. The recommended operating range is 1.5V to 5.5V, making it compatible with 1.8V, 2.7V, 3.3V, and 5V systems. Always use a 0.1μF ceramic bypass capacitor between V+ and GND, placed adjacent to the device pins, to ensure stable operation under transient load conditions.

Does TLV341AIDCKTG4 support true rail-to-rail input common-mode range?

TLV341AIDCKTG4 supports 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 allows direct connection of sensors referenced to GND in single-supply configurations. The PMOS input stage enables operation with inputs at or slightly below ground, critical for transducer interfaces where negative signal excursions occur.

How does the shutdown feature behave electrically in TLV341AIDCKTG4?

When the SHDN pin is pulled low (<0.2V), TLV341AIDCKTG4 enters shutdown mode with typical supply current reduced to 10pA per channel and output placed in high-impedance state. The output remains disconnected from internal circuitry, preventing loading of downstream stages. Turn-on time from shutdown is 5μs typical, measured from SHDN rising above 1.5V (at V+ = 1.8V) to output settling within 1% of final value.

What is the guaranteed input offset voltage specification for TLV341AIDCKTG4 over temperature?

TLV341AIDCKTG4 (A grade) guarantees maximum input offset voltage of 1.7mV over the full operating temperature range of –40°C to +125°C. At 25°C, the limit is tighter: 1.25mV maximum. This DC precision, combined with 1.9μV/°C typical drift, makes it suitable for applications like battery fuel gauging and precision current sensing where offset stability across environmental conditions is critical.

Can TLV341AIDCKTG4 drive a 600Ω load in audio applications?

TLV341AIDCKTG4 is not optimized for 600Ω loads: its output short-circuit current is ±12mA (sourcing) and ±20mA (sinking) at 5V, limiting usable output swing under heavy load. For 1V_PP audio signals into 600Ω, THD+N is 0.012% at 1kHz, but output swing degrades significantly. It is best applied in line-level buffering (≥10kΩ load) or as a preamp stage preceding a dedicated audio driver IC.
