Texas Instruments TLV341IDCKTG4

Overview

TLV341IDCKTG4 from Texas Instruments is a single-channel, low-voltage, rail-to-rail output CMOS operational amplifier with active-low shutdown control, designed for 1.5V–5.5V single-supply operation. It delivers 2.3MHz gain bandwidth, 0.9V/μs slew rate, and ultra-low 70μA supply current per channel - enabling precision signal conditioning in space-constrained, battery-powered systems such as portable audio preamplifiers and supply current monitors.

For engineers reviewing the TLV341IDCKTG4 datasheet, TLV341IDCKTG4 pinout, TLV341IDCKTG4 application, or TLV341IDCKTG4 equivalent, key selection criteria include its 1.25mV max input offset (A grade), 1pA typical input bias current, rail-to-rail output swing within 20mV of rails (at 10kΩ load), shutdown current of 10pA typical, and SC70-6 package compatibility with high-density PCB layouts.

Technical Context

The TLV341IDCKTG4 employs a PMOS input stage enabling common-mode input range from –0.2V to (V+ – 0.5V), including ground reference, and a CMOS output stage supporting rail-to-rail swing. Its shutdown function places the output in high-impedance state while reducing supply current to ≤1μA (typical 10pA), with 5μs turnon time.

It operates across –40°C to +125°C and supports stable closed-loop performance with ≥55° phase margin at 5V supply and 100kΩ load with 200pF capacitive load - validated for use in DC-coupled sensor interfaces and low-noise filtering where input offset drift (<1.9μV/°C) and voltage noise (20nV/√Hz at 10kHz) are critical.

FAQ

What is the maximum supply voltage rating for TLV341IDCKTG4?

The absolute maximum supply voltage for TLV341IDCKTG4 is 5.5V. Operation above this level risks permanent damage. Recommended operating range is 1.5V to 5.5V, with full electrical specifications guaranteed across that span. At 5V supply, it delivers 2.3MHz GBW and 1V/μs slew rate - confirming robust performance at upper rail.

Does TLV341IDCKTG4 support true rail-to-rail input common-mode range?

TLV341IDCKTG4 supports a wide input common-mode range from –0.2V to (V+ – 0.5V), which includes ground but does not extend fully to V+. Its PMOS input stage enables operation with inputs at 0V, making it suitable for single-supply sensor interfaces where the signal references GND - unlike bipolar-input op-amps that require headroom above ground.

How does the shutdown feature of TLV341IDCKTG4 behave electrically?

When the SHDN pin is pulled low (≤0.2V), TLV341IDCKTG4 enters shutdown mode: supply current drops to ≤1μA (typically 10pA), and the output transitions to high-impedance state. The 5μs typical turnon time ensures rapid reactivation. During shutdown, input pins remain high-impedance, and internal biasing is disabled - preventing unintended current paths or signal coupling.

Can TLV341IDCKTG4 drive capacitive loads reliably?

TLV341IDCKTG4 maintains ≥55° phase margin with 200pF capacitive load at 100kΩ feedback resistance (per datasheet Figure 5-24). For heavier loads (>500pF), external isolation resistance (e.g., 10–50Ω in series with output) is recommended. Its CMOS output stage avoids phase reversal but requires careful layout - especially short traces and local bypassing - to sustain stability in high-C_L applications like LCD bias buffers.

Is TLV341IDCKTG4 specified for operation at –40°C to +125°C?

Yes, TLV341IDCKTG4 is fully specified and tested across –40°C to +125°C. Key parameters - including input offset voltage (max 1.7mV), supply current (max 215μA), and output swing - are guaranteed over this extended industrial temperature range. This makes it suitable for under-hood automotive modules, industrial motor controllers, and outdoor IoT gateways where ambient extremes are expected.
