Texas Instruments TLV341AIDCKT

Overview

TLV341AIDCKT from Texas Instruments is a single-channel, low-voltage, rail-to-rail output CMOS operational amplifier with active-low shutdown control, 1.25 mV max input offset voltage (25°C, A grade), 2.3 MHz gain bandwidth, and 70 µA typical supply current per channel - designed for precision signal conditioning in space-constrained, battery-powered systems such as portable audio preamplifiers and supply current monitoring circuits.

For engineers reviewing the TLV341AIDCKT datasheet, TLV341AIDCKT pinout, TLV341AIDCKT application, or TLV341AIDCKT equivalent, key selection criteria include its 1.5 V to 5.5 V single-supply operation, –40°C to 125°C extended temperature range, ultra-low 1 pA typical input bias current, 5 µs typical turnon time from shutdown, and SC70-6 package compatibility with high-density PCB layouts.

Technical Context

The TLV341AIDCKT employs a PMOS input stage enabling rail-to-rail common-mode input range down to ground (–0.2 V) and up to (V+ – 0.5 V), while its CMOS output stage delivers true rail-to-rail swing with <25 mV drop at 10 kΩ load. Its shutdown function reduces supply current to 10 pA typical per channel and places the output in high-impedance state.

Designed for direct-coupled, low-offset applications, the A-grade variant guarantees ≤1.25 mV input offset voltage at 25°C and ≤1.7 mV across –40°C to 125°C, with 1.9 µV/°C average temperature coefficient - making it suitable for precision DC-coupled sensor interfaces and battery voltage monitoring where thermal drift must be minimized.

FAQ

What is the maximum supply voltage rating for TLV341AIDCKT?

The absolute maximum supply voltage for TLV341AIDCKT is 5.5 V. Operation above this level risks permanent damage per TI SLVS568E Section 5.1. Recommended operating range is 1.5 V to 5.5 V, supporting single-cell Li-ion (up to 4.2 V), two-cell alkaline (3.2 V), and standard 3.3 V logic rails. Always use a 0.1 µF ceramic bypass capacitor between V+ and GND, placed adjacent to the device.

Does TLV341AIDCKT support true rail-to-rail input?

TLV341AIDCKT supports rail-to-rail output swing but has a limited rail-to-rail input range: common-mode voltage extends from –0.2 V to (V+ – 0.5 V). This includes ground but does not reach the positive rail. For example, at V+ = 1.8 V, usable input range is –0.2 V to 1.3 V; at V+ = 5 V, it is –0.2 V to 4.5 V. Input overvoltage beyond these limits may degrade CMRR or cause phase reversal.

How does the shutdown feature behave on TLV341AIDCKT?

TLV341AIDCKT's SHDN pin is active-low: pulling it to GND places the amplifier in shutdown mode, reducing supply current to 10 pA typical per channel and forcing the output into high-impedance state. Normal operation resumes when SHDN is pulled to ≥1.5 V (at 1.8 V supply) or ≥4.5 V (at 5 V supply). Turnon time from shutdown is 5 µs typical, verified per Section 5.9–5.10 of the datasheet.

What is the guaranteed input offset voltage specification for TLV341AIDCKT?

TLV341AIDCKT is an A-grade device with guaranteed maximum input offset voltage of 1.25 mV at 25°C, 1.5 mV from 0°C to 125°C, and 1.7 mV across the full –40°C to 125°C operating range. Typical offset is 0.3 mV. This specification is validated per TI SLVS568E Sections 5.7–5.8 and enables high-accuracy DC-coupled applications without external trimming or auto-zero circuitry.

Which package type corresponds to the TLV341AIDCKT part number?

TLV341AIDCKT uses the SC70-6 (DCK) package: a 6-pin surface-mount outline measuring 2.00 mm × 1.25 mm with 0.65 mm lead pitch. This is distinct from the SOT-23-6 (DBV) and SOT-6 (DRL) variants. The DCK package offers superior thermal resistance (RθJA = 196.8°C/W) and board-level reliability for compact portable designs, as documented in TI SLVS568E Section 10.
