Product details
Overview
TSV914AIPWR from Texas Instruments is a quad-channel rail-to-rail input/output operational amplifier optimized for general-purpose signal conditioning in space-constrained, low-power systems. It delivers 8-MHz gain bandwidth, 18 nV/√Hz input voltage noise at 1 kHz, 550 µA typical quiescent current per amplifier, and operates from 2.5 V to 5.5 V supply - enabling use in battery-powered sensor front-ends and motor control feedback loops.
For engineers reviewing the TSV914AIPWR datasheet, TSV914AIPWR pinout, TSV914AIPWR application, or TSV914AIPWR equivalent, key selection criteria include its rail-to-rail I/O swing across full temperature range (–40°C to 125°C), ultra-low 1 pA typical input bias current for high-impedance sensor interfaces, and unity-gain stability with no phase reversal under overdrive.
Technical Context
The TSV914AIPWR implements 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 V–5.5 V operation. Its unity-gain stable architecture supports direct driving of SAR ADC inputs without external compensation.
Each of the four amplifiers features independent output stages with 4.5 V/µs slew rate and 0.5 µs 0.1% settling time (2-V step, CL = 100 pF), while maintaining low THD+N (0.0008% at 1 kHz) and high channel separation (>100 dB DC). Input offset voltage is specified at ±1.5 mV max (TA = 25°C) with ±0.5 µV/°C typical drift.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load or next-stage input; rail-to-rail swing supports full 0–5.5 V dynamic range. |
| 2 | –IN A | Inverting input, channel A - accepts feedback network for inverting configurations; high impedance minimizes loading on preceding stage. |
| 3 | +IN A | Noninverting input, channel A - used for unity-gain buffers or high-Z sensor connections; CMVR extends beyond rails. |
| 4 | V+ | Positive supply - connects to main system rail (2.5–5.5 V); decoupling capacitor required within 1 cm. |
| 5 | +IN B | Noninverting input, channel B - electrically isolated from channel A; enables dual-sensor simultaneous acquisition. |
| 6 | –IN B | Inverting input, channel B - shares no internal nodes with channel A; supports independent gain setting. |
| 7 | OUT B | Amplifier B output - independently driven; no crosstalk with channels A/C/D per 100+ dB channel separation. |
| 8 | OUT C | Amplifier C output - identical electrical specs to OUT A/B; enables multi-axis sensor signal conditioning. |
| 9 | –IN C | Inverting input, channel C - supports differential-to-single-ended conversion with matched layout to +IN C. |
| 10 | +IN C | Noninverting input, channel C - referenced to same ground as all other inputs; maintains rail-to-rail CMVR. |
| 11 | V– | Negative supply / ground - must be connected directly to PCB ground plane; serves as reference for all four amplifiers. |
| 12 | +IN D | Noninverting input, channel D - enables fourth independent signal path; matches input capacitance (4 pF common-mode) of other channels. |
| 13 | –IN D | Inverting input, channel D - supports programmable gain instrumentation amp topologies using external resistors. |
| 14 | OUT D | Amplifier D output - fully specified for capacitive loads up to 300 pF; overshoot limited to ±60% per characterization data. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6004-E/SL | Lower GBW (1 MHz), higher input offset (±3 mV max), no EMI filtering; 1.8–6.0 V supply. | Not suitable for high-speed active filters or precision current sensing where TSV914AIPWR's 8-MHz bandwidth or 1.5-mV offset matters. | Select when cost sensitivity outweighs speed/precision needs and EMI immunity is non-critical. |
| LMV324IDR | Higher quiescent current (130 µA per amp → 520 µA total), lower PSRR (65 dB), no guaranteed 125°C operation. | Limited to commercial-temperature consumer devices; insufficient for automotive HVAC or industrial motor control ambient conditions. | Choose only for cost-driven, room-temperature applications where 4.5 V/µs slew rate and 125°C rating are unnecessary. |
Compared with MCP6004-E/SL and LMV324IDR, TSV914AIPWR offers superior bandwidth-noise-power trade-off, guaranteed extended temperature performance, and integrated EMI hardening - making it the preferred choice for precision, high-reliability embedded systems.

FAQ
What is the maximum capacitive load the TSV914AIPWR can drive while maintaining stability?
The TSV914AIPWR is characterized for stable operation with capacitive loads up to 300 pF, as shown in Figure C025 and C026 of the SBOS878D datasheet. Overshoot remains within ±60% at 300 pF, and phase margin stays above 55° across the full 2.5–5.5 V supply range. For loads >100 pF, TI recommends adding a small series resistor (10–50 Ω) between output and load to isolate capacitance.
Does the TSV914AIPWR support true rail-to-rail input common-mode voltage range?
Yes, the TSV914AIPWR supports rail-to-rail input common-mode voltage range - extending 100 mV beyond both supply rails (V– – 0.1 V to V+ + 0.1 V) across its full 2.5 V–5.5 V supply range. This is achieved via a complementary N/P-channel input stage, enabling accurate signal acquisition near supply rails in single-supply systems.
What is the thermal resistance (RθJA) of the TSV914AIPWR in its SOIC package?
The TSV914AIPWR in the 14-pin SOIC package (D) has a junction-to-ambient thermal resistance (RθJA) of 106.9°C/W, as specified in Section 7.6 of the SBOS878D datasheet. This value assumes standard JEDEC 2-layer board conditions (1-inch² copper pad, 2 oz Cu). Actual board layout significantly impacts thermal performance.
Can the TSV914AIPWR be used in single-supply 3.3-V applications?
Yes, the TSV914AIPWR is fully specified for operation from 2.5 V to 5.5 V, including 3.3-V single-supply systems. Its rail-to-rail input and output allow full utilization of the 0–3.3 V range, and parameters such as input offset voltage (±1.5 mV max), GBW (8 MHz), and quiescent current (550 µA per amp) are guaranteed across this supply range.
Is the TSV914AIPWR pin-compatible with other members of the TSV91x family?
No - the TSV914AIPWR (14-pin SOIC) is not pin-compatible with the TSV911 (5-pin) or TSV912 (8-pin) variants. Pin counts, pin functions, and physical footprints differ across the family. However, electrical specifications (GBW, noise, supply range, etc.) are closely matched, enabling functional substitution with PCB layout changes.
