Product details
Overview
TSV912AIPWR from Texas Instruments is a dual-channel rail-to-rail input/output operational amplifier optimized for low-power, precision signal conditioning in single-supply systems. It delivers 8 MHz gain bandwidth, 550 µA typical quiescent current per amplifier, and ±1.5 mV maximum input offset voltage across –40°C to 125°C - enabling high-accuracy sensor interfacing in battery-powered HVAC controllers and motor control feedback loops.
For engineers reviewing the TSV912AIPWR datasheet, TSV912AIPWR pinout, TSV912AIPWR application, or TSV912AIPWR equivalent, key selection criteria include its rail-to-rail I/O swing at 2.5–5.5 V supply, ultra-low 1 pA input bias current for high-impedance sources, and unity-gain stability with no phase reversal under overdrive - critical for active filtering and medical instrumentation front-ends.
Technical Context
The TSV912AIPWR employs a complementary differential input stage (N- and P-channel pairs) enabling true rail-to-rail common-mode input range - extending 100 mV beyond both supply rails across 2.5–5.5 V operation. Its unity-gain stable architecture supports direct ADC driving without external compensation.
It features integrated RFI/EMI rejection filtering, ±4-kV HBM ESD protection, and robust overload recovery (<0.2 µs), making it suitable for noisy industrial environments. The device maintains 80 dB minimum CMRR and 100 dB open-loop gain at 2 kΩ load, ensuring stable closed-loop performance in precision gain stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth | 8 MHz - enables stable unity-gain operation and supports >100 kHz closed-loop bandwidth in sensor amplifiers. |
| Supply Voltage | 2.5 V to 5.5 V - compatible with Li-ion, USB, and 3.3 V/5 V system rails without level-shifting. |
| Input Offset Voltage | ±1.5 mV max - ensures ≤0.03% gain error in 50 mV full-scale current-sense applications. |
| Quiescent Current | 550 µA per channel typ - allows dual-amplifier operation on <1.1 mA total, ideal for always-on battery nodes. |
| Input Bias Current | 1 pA typ - preserves accuracy with >100 MΩ source impedances (e.g., pH electrodes, piezoresistive sensors). |
| CMRR | 80 dB min (–40°C to 125°C) - rejects common-mode noise in motor current sensing with shunt resistors. |
| Slew Rate | 4.5 V/µs - supports 2-V step settling within 0.5 µs to 0.1%, sufficient for 12-bit SAR ADC sampling. |
Pinout & Package
TSV912AIPWR is housed in an 8-pin SOIC (D) package measuring 3.91 mm × 4.90 mm, with exposed thermal pad connected to V– for enhanced power dissipation in continuous operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to 10 kΩ while maintaining rail-to-rail swing. |
| 2 | –IN A | Inverting input for channel A - accepts signals from 100 mV below V– to 100 mV above V+. |
| 3 | +IN A | Noninverting input for channel A - used for unity-gain buffers or high-Z sensor interfaces. |
| 4 | V– | Negative supply or ground - also connects to exposed thermal pad for thermal management. |
| 5 | +IN B | Noninverting input for channel B - enables dual independent signal paths (e.g., differential pair + reference). |
| 6 | –IN B | Inverting input for channel B - supports matched gain configurations with channel A. |
| 7 | OUT B | Amplifier B output - electrically isolated from OUT A; shares same supply rails. |
| 8 | V+ | Positive supply - supplies both amplifiers; decoupling capacitor required at pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 3.3 V systems - e.g., 0–3.3 V ADC input without clipping. |
| Low input bias current (1 pA) | Prevents signal degradation in high-impedance pH or photodiode circuits where leakage would dominate error. |
| No phase reversal in overdrive | Eliminates latch-up risk during transient overvoltage events - critical for motor current sense in fault conditions. |
| Integrated RFI-EMI rejection filter | Reduces susceptibility to 100 MHz–1 GHz RF interference in automotive infotainment power domains. |
| Extended temperature range (–40°C to 125°C) | Validated for under-hood automotive and industrial PLC modules without derating. |
Applications
| Motor Control Feedback | Medical Sensor Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6022-I/SN | Lower GBP (10 MHz), higher IQ (1 mA/ch), no integrated EMI filter | Limited to <85°C ambient; less robust in RF-noisy HVAC blower compartments | Preferred when higher speed is needed and thermal margin exists |
| LMV358IDR | Wider offset (±3 mV max), lower PSRR (65 dB), no rail-to-rail input | Cannot interface directly with 0 V-referenced sensors; requires level-shifting circuitry | Selected only for cost-sensitive, non-precision applications with 5 V supply |
Compared with MCP6022-I/SN and LMV358IDR, TSV912AIPWR offers superior input offset accuracy, guaranteed rail-to-rail input operation down to 2.5 V, and built-in EMI filtering - making it the optimal choice for precision, low-voltage, noise-immune designs in medical and automotive-qualified systems.

FAQ
What is the operating supply voltage range for TSV912AIPWR?
The TSV912AIPWR operates from 2.5 V to 5.5 V total supply voltage (V+ to V–), supporting single-supply configurations down to 2.5 V logic levels. This range enables direct compatibility with Li-ion batteries (3.0–4.2 V), USB-powered devices (5 V), and 3.3 V microcontroller systems without voltage translation - a key enabler for compact, low-power designs where TSV912AIPWR is deployed in sensor signal chains.
Does TSV912AIPWR support rail-to-rail input and output simultaneously?
Yes, TSV912AIPWR supports true rail-to-rail input and output operation across its full 2.5–5.5 V supply range. Its complementary input stage allows common-mode input voltages from (V–) – 0.1 V to (V+) + 0.1 V, and output swings within 15 mV of each rail at 10 kΩ load. This capability is verified in the TSV912AIPWR datasheet Figures 3–5 and enables full-scale utilization of ADC inputs without external biasing - a core design advantage in TSV912AIPWR applications like medical sensor front-ends.
What is the typical quiescent current per channel for TSV912AIPWR?
The TSV912AIPWR draws 550 µA typical quiescent current per amplifier at 5.5 V supply, with a maximum of 750 µA over temperature. At 2.5 V, IQ remains stable near 550 µA, making TSV912AIPWR highly efficient for dual-channel operation in battery-critical systems. This low power consumption - confirmed in Section 7.7 of the TSV912AIPWR datasheet - directly enables multi-year operation in wireless HVAC sensors and portable diagnostic tools using TSV912AIPWR.
Is TSV912AIPWR unity-gain stable?
Yes, TSV912AIPWR is explicitly specified as unity-gain stable in its datasheet (Section 8.1 and Figure 6). It achieves ≥55° phase margin at G = 1 with 100 pF capacitive load, eliminating the need for external compensation networks. This stability is essential for TSV912AIPWR use cases such as ADC driver buffers and active filters - where unpredictable oscillation or overshoot would compromise measurement integrity in systems relying on TSV912AIPWR's precision performance.
What package type does TSV912AIPWR use, and does it include thermal enhancement?
TSV912AIPWR uses the 8-pin SOIC (D) package (3.91 mm × 4.90 mm) with an exposed thermal pad on the underside, which must be soldered to V– for optimal thermal performance. Thermal data in Section 7.5 shows RθJA = 157.6°C/W for this variant - significantly lower than WSON or SOT-23 alternatives. This thermal design makes TSV912AIPWR suitable for sustained operation in enclosed HVAC control modules where TSV912AIPWR may drive moderate loads continuously without derating.
