Product details
Overview
TSV6295AIPT from STMicroelectronics is a quad micropower CMOS operational amplifier with rail-to-rail input and output, 1.3 MHz gain bandwidth product, 29 µA typical supply current per amplifier, and dual independent shutdown control (SHDN1/2 and SHDN3/4). It operates from 1.5 V to 5.5 V and supports precision sensor signal conditioning in battery-powered medical instrumentation.
For engineers reviewing the TSV6295AIPT datasheet, TSV6295AIPT pinout, TSV6295AIPT application, or TSV6295AIPT equivalent, key selection considerations include minimum stable gain (+4 non-inverting / –3 inverting), shutdown current of 5 nA typ at 1.8 V, input offset voltage ≤800 µV (A-grade), EMI hardening, and operation across –40°C to +125°C.
Technical Context
The TSV6295AIPT employs complementary PMOS/NMOS input stages enabling rail-to-rail input common-mode range (VCC– – 0.1 V to VCC+ + 0.1 V) and achieves 80 dB typical CMRR at 5 V. Its internal compensation ensures stability only at gains ≥+4 (non-inverting) or ≤–3 (inverting), with phase margin ≥60° under specified load conditions (RL = 10 kΩ, CL = 20 pF).
Each amplifier features independent shutdown logic with VIH = 2 V and VIL = 0.8 V at VCC = 5 V, turn-on time of 200 ns, and high-impedance output state during shutdown. Input bias current is 1 pA typ, supporting high-impedance source interfacing without significant error.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - enables direct use with single-cell Li-ion, NiMH, or 3.3 V/5 V rails without LDO. |
| Gain Bandwidth Product | 1.3 MHz typ at VCC = 5 V - supports audio-band filtering and fast sensor signal amplification up to ~100 kHz closed-loop. |
| Supply Current per Amp | 29 µA typ - allows four-channel operation at <116 µA total, critical for multi-sensor nodes with 10+ year battery life. |
| Input Offset Voltage | ≤800 µV max (A version) - ensures ≤0.8 mV DC error in 1× gain configurations, suitable for precision bridge sensor interfaces. |
| Shutdown Current | 5 nA typ at 1.8 V - reduces quiescent power to <10 nW per channel, enabling ultra-low-power duty-cycled sensing. |
| EMI Rejection Ratio | 92 dB at 1800 MHz - suppresses cellular band interference in portable medical devices without external shielding. |
| Rail-to-Rail Output Swing | Within 35 mV of rails (RL = 10 kΩ) - maximizes dynamic range in low-voltage ADC front-ends (e.g., 12-bit SAR at 3.3 V). |
Pinout & Package
TSSOP-16 package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, 16-pin surface-mount, ECOPACK® compliant, rated for –40°C to +125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7 | In1+, In2+, In3+, In4+ | Non-inverting inputs - accept signals from 0.1 V below VCC– to 0.1 V above VCC+, enabling full-supply-range sensor interfacing. |
| 2, 4, 6, 8 | In1–, In2–, In3–, In4– | Inverting inputs - support differential, transimpedance, or inverting gain configurations with matched input impedance. |
| 9, 11, 13, 15 | Out1, Out2, Out3, Out4 | Amplifier outputs - deliver rail-to-rail swing into ≥10 kΩ loads; high-Z in shutdown mode. |
| 10, 12 | SHDN1/2, SHDN3/4 | Independent shutdown controls - active-high logic; each pair disables two amplifiers, enabling selective channel power gating. |
| 14 | VCC+ | Positive supply - accepts 1.5–5.5 V; requires local 10 nF decoupling per datasheet layout recommendation. |
| 16 | VCC– | Negative supply / ground reference - must be tied to system ground; not floating. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Extends usable input common-mode range to VCC– – 0.1 V to VCC+ + 0.1 V and output swing to within 35 mV of both rails - preserves full ADC resolution in low-voltage systems. |
| Ultra-low input bias current | 1 pA typ - eliminates leakage-induced offset in high-impedance pH, ion-selective, or piezoelectric sensor interfaces (>1 GΩ sources). |
| EMI-hardened architecture | 92 dB rejection at 1800 MHz - prevents RF rectification artifacts in cellular-connected wearables and portable diagnostics. |
| Independent dual shutdown | Two dedicated SHDN pins (pins 10 & 12) - allow selective deactivation of amplifier pairs to reduce power by >99.9% per disabled channel. |
| Extended temperature operation | Specified from –40°C to +125°C - supports under-hood automotive sensors, industrial process monitors, and sterilizable medical probes. |

IC Role / Device Role / Timing Role: One amplifier serves as precision current-source controller, another as ratiometric reference buffer, third as cold-junction compensation, fourth as fault monitor. Use Value: –40°C to +125°C rating ensures reliability in uncontrolled enclosures; 4 kV HBM ESD protects against field maintenance events. |
Use Scenario: Implementing a 2nd-order low-pass filter (fc = 5 kHz) in a rechargeable hearing aid with 1.2 V NiMH supply. IC Role / Device Role / Timing Role: Two amplifiers form Sallen-Key topology; remaining two provide microphone preamp and receiver driver with shutdown between audio frames.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV6295IPT | Standard grade (Vio ≤ 1 mV max vs. 0.8 mV max for A-version); same pinout, specs, and shutdown function. | Suitable for cost-sensitive consumer applications where 200 µV higher offset is acceptable. | Select when budget constraints outweigh need for highest DC accuracy in medical or industrial use cases. |
| TSV6395IPT | Higher supply current (60 µA vs. 29 µA), unity-gain stable, 2.4 MHz GBP, no shutdown pins. | Used where gain = 1 is required or higher bandwidth justifies 2× power increase; lacks channel-level power gating. | Choose for unity-gain buffer applications or when faster response (e.g., >500 kHz closed-loop) is mandatory and battery life is secondary. |
Compared with TSV6295IPT, the A-grade offers tighter offset for precision DC measurement; compared with TSV6395IPT, it trades bandwidth and unity-gain stability for micropower operation and independent shutdown-critical for energy-constrained multi-channel sensing.

FAQ
What is the minimum recommended gain configuration for stable operation of TSV6295AIPT?
The TSV6295AIPT is not unity-gain stable and requires a minimum closed-loop gain of +4 in non-inverting configurations or –3 in inverting configurations to ensure ≥60° phase margin. This is verified with RL = 10 kΩ and CL = 20 pF at 25°C. Using lower gains risks oscillation, especially with capacitive loads.
How does the shutdown function behave on pins 10 and 12?
Pin 10 (SHDN1/2) disables amplifiers 1 and 2; pin 12 (SHDN3/4) disables amplifiers 3 and 4. Both are active-high: pulling either pin to VCC+ enables its pair, while pulling to VCC– places outputs in high-impedance state and reduces supply current to 5 nA typ per disabled pair. Pins must never float.
Can TSV6295AIPT drive a 100 kΩ load with rail-to-rail output swing?
Yes - rail-to-rail output swing (within 35 mV of rails) is guaranteed with RL ≥ 10 kΩ. At 100 kΩ, output swing improves further (typically within 15 mV), and THD+N remains ≤0.03% at 1 kHz. However, slew rate decreases slightly due to reduced output current capability at higher impedances.
Is TSV6295AIPT compatible with PCB layouts using 0402 or 0603 passive decoupling?
Yes - the datasheet specifies placement of 10 nF ceramic decoupling capacitors as close as possible to pins 14 (VCC+) and 16 (VCC–). 0402 or 0603 case sizes are fully appropriate; layout priority is minimizing trace inductance (<2 mm length) rather than capacitor footprint size.
