Texas Instruments TSV912AIDGKT

Overview

TSV912AIDGKT from Texas Instruments is a dual-channel rail-to-rail input/output operational amplifier optimized for precision, low-power, single-supply applications. It delivers 8 MHz gain bandwidth, 18 nV/√Hz input voltage noise at 1 kHz, 550 µA typical quiescent current per amplifier, and ±1 pA typical input bias current - enabling high-accuracy sensor signal conditioning in battery-powered medical instrumentation and motor control systems.

For engineers reviewing the TSV912AIDGKT datasheet, TSV912AIDGKT pinout, TSV912AIDGKT application, or TSV912AIDGKT equivalent, key selection criteria include its rail-to-rail I/O swing across 2.5 V–5.5 V supply, –40°C to 125°C operating range, unity-gain stability with capacitive loads up to 300 pF, and low 1.5 mV max input offset voltage for DC-critical signal chains.

Technical Context

The TSV912AIDGKT employs a complementary differential input stage (N- and P-channel pairs) to achieve rail-to-rail common-mode input range extending 100 mV beyond both supply rails across 2.5 V–5.5 V operation. Its unity-gain stable architecture supports direct driving of SAR ADC inputs without external compensation.

It features integrated RFI-EMI rejection filtering, no phase reversal under overdrive, and robust ±4-kV HBM ESD protection. The dual-channel configuration shares a common 8-pin SOIC package with independent, non-interacting amplifiers - each with matched AC/DC performance and thermal tracking across temperature.

Key Specifications

Pinout & Package

FAQ

What is the maximum capacitive load the TSV912AIDGKT can drive while remaining stable?

The TSV912AIDGKT maintains unity-gain stability with capacitive loads up to 300 pF, as verified by overshoot vs. load capacitance curves in the datasheet (Figure C025). For loads exceeding 300 pF, external isolation resistance (e.g., 10–50 Ω in series with the output) is required to preserve phase margin above 55° and prevent ringing in step response.

Does the TSV912AIDGKT support true single-supply operation down to 2.5 V?

Yes, the TSV912AIDGKT is fully specified from 2.5 V to 5.5 V supply. Its rail-to-rail input extends 100 mV beyond both rails, and output swings within 15 mV of each rail at 5.5 V - enabling accurate signal conditioning in 2.5 V microcontroller systems without level-shifting components.

How does the TSV912AIDGKT handle input overvoltage conditions?

The TSV912AIDGKT incorporates internal ESD diodes clamping input pins to the supply rails (V+ and V–), limiting input current to ±10 mA if signals exceed (V–) – 0.5 V or (V+) + 0.5 V. This protects against transient overvoltage but requires external current limiting for sustained overvoltage events beyond absolute maximum ratings.

Is the exposed thermal pad on the TSV912AIDGKT SOIC package electrically active?

No - the exposed thermal pad on the TSV912AIDGKT (SOIC-D package) is internally connected to V– and must be soldered to a PCB ground plane for optimal thermal performance and EMI suppression. It is not isolated and should never be left floating or connected to any other potential.

What is the typical input offset voltage drift of the TSV912AIDGKT over temperature?

The TSV912AIDGKT has a typical input offset voltage drift of ±0.5 µV/°C across –40°C to 125°C, as specified in the Electrical Characteristics table. This low drift ensures minimal calibration drift in precision temperature measurement circuits using RTDs or thermistors over wide ambient ranges.
