Product details
Overview
TSV6295IPT 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 is specified for -40°C to +125°C, making it suitable for low-power sensor signal conditioning in portable medical instrumentation.
For engineers reviewing the TSV6295IPT datasheet, TSV6295IPT pinout, TSV6295IPT application, or TSV6295IPT equivalent, key selection considerations include its minimum stable gain requirement (+4 non-inverting / -3 inverting), 5 nA typical shutdown current, 800 µV max input offset voltage (A version), and TSSOP-16 package compatibility with high-density PCB layouts.
Technical Context
The TSV6295IPT integrates four independent amplifiers sharing a common supply (VCC+, VCC−) and two dedicated shutdown pairs (SHDN1/2 controls Amps 1 & 2; SHDN3/4 controls Amps 3 & 4), enabling selective power gating. Its complementary PMOS/NMOS input stage delivers rail-to-rail input common-mode range (VCC− −0.1 V to VCC+ +0.1 V) and eliminates phase reversal.
Stability requires closed-loop gain ≥ +4 (non-inverting) or ≤ −3 (inverting) due to internal compensation optimized for 1.3 MHz GBP at 29 µA. EMI hardening (61–92 dB EMIRR across 400–2400 MHz) and 4 kV HBM ESD tolerance support robust operation in noisy portable environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.5 V to 5.5 V - enables direct battery operation (single-cell Li-ion or two alkaline cells) without regulation. |
| Gain Bandwidth Product | 1.3 MHz typ - supports active filtering up to ~100 kHz with gain ≥ +4 while maintaining phase margin ≥60°. |
| Supply Current per Amp | 29 µA typ - allows four-channel amplification with total quiescent current under 120 µA at 1.8 V. |
| Input Offset Voltage | 800 µV max (A version) - ensures <0.5% error in 0.16 V full-scale sensor outputs (e.g., thermopile or bridge sensors). |
| Shutdown Current | 5 nA typ per amplifier - reduces total system standby power to <20 nA when all four amps are disabled. |
| Input Bias Current | 1 pA typ - preserves signal integrity in high-impedance pH or photodiode front-ends without loading. |
| EMI Rejection Ratio | 92 dB at 1800 MHz - mitigates cellular interference in wearable ECG or pulse oximeter designs. |
Pinout & Package
TSSOP-16 package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, 1.2 mm height, RoHS-compliant ECOPACK®2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7 | In1+, In2+, In3+, In4+ | Non-inverting inputs - accept signals from VCC− −0.1 V to VCC+ +0.1 V with no phase reversal. |
| 2, 4, 6, 8 | In1−, In2−, In3−, In4− | Inverting inputs - enable precision differential, inverting, or transimpedance configurations. |
| 9, 11, 13, 15 | Out1, Out2, Out3, Out4 | Rail-to-rail outputs - swing within 35 mV of rails into 10 kΩ load, supporting low-voltage ADC interfacing. |
| 10, 12 | SHDN1/2, SHDN3/4 | Independent shutdown controls - logic-high enables corresponding amplifier pair; logic-low disables with high-Z output. |
| 14 | VCC+ | Positive supply - accepts 1.5–5.5 V; decoupling capacitor required within 2 mm for stability. |
| 16 | VCC− | Negative supply - typically ground; serves as reference for shutdown logic thresholds (VIH = 2 V, VIL = 0.8 V @ 5 V). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input/output | Enables full dynamic range utilization in single-supply systems (e.g., 1.8 V microcontroller ADC reference). |
| Dual independent shutdown | Reduces power by >99.9% per disabled amplifier pair-critical for duty-cycled sensor nodes. |
| EMI-hardened architecture | Rejects RF interference from GSM/Bluetooth bands without external filtering, simplifying layout. |
| Extended temperature range | Guaranteed operation from −40°C to +125°C-validates use in automotive cabin or industrial motor control enclosures. |
| Low input bias current | 1 pA typ prevents signal loss in megohm-range sensor interfaces (e.g., electrochemical gas sensors). |
Applications
| Portable ECG Monitor | Wireless Sensor Node |
|---|---|
|
Use Scenario: Amplifying low-amplitude (<1 mV), high-impedance biopotential signals from dry electrodes in battery-powered ECG patches. IC Role / Device Role / Timing Role: Quad amplifier configures two channels of instrumentation amplifier (In1+/In1−, In2+/In2−) plus two buffer stages (In3+/In3−, In4+/In4−) for ADC drive. Use Value: 1 pA input bias current avoids electrode polarization errors; 29 µA per amp extends 2-week battery life on CR2032. |
Use Scenario: Signal conditioning for MEMS accelerometer and temperature sensor in LoRaWAN edge node with intermittent wake-up. IC Role / Device Role / Timing Role: One amplifier channel conditions accelerometer output; second handles thermistor voltage divider; remaining two held in shutdown during sleep. Use Value: Dual shutdown pins allow independent control-reducing active time current to 58 µA and sleep current to 20 nA. |
| Industrial Pressure Transmitter | Wearable Pulse Oximeter |
|
Use Scenario: Amplifying millivolt-level output from silicon piezoresistive pressure bridge in 4–20 mA loop-powered transmitter. IC Role / Device Role / Timing Role: Precision non-inverting amplifier (gain = +10) with rail-to-rail output drives 12-bit DAC reference; fourth amp buffers reference voltage. Use Value: 800 µV max Vio ensures <0.1% FS error over −40°C to +125°C; 4 kV HBM withstands field ESD events. |
Use Scenario: Dual-wavelength (660 nm/940 nm) photodiode current-to-voltage conversion and AC-coupled amplification in compact earbud form factor. IC Role / Device Role / Timing Role: Two transimpedance amplifiers (In1−/Out1, In2−/Out2); third amp AC-couples LED driver feedback; fourth buffers ADC reference. Use Value: 1.3 MHz GBP supports 100 Hz pulse detection bandwidth; 92 dB EMIRR suppresses 1800 MHz LTE noise in proximity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV6295IST | TSSOP-14 package, no SHDN3/4 - only one shared shutdown for all four amplifiers. | Lacks independent shutdown control; unsuitable for partial-channel power gating. | Select when board space constraints favor TSSOP-14 and full-array shutdown suffices. |
| TSV6395IPT | 60 µA supply current, 2.4 MHz GBP, unity-gain stable - higher speed/power trade-off. | Supports gain = +1 configurations; better for wideband active filters but doubles quiescent current. | Choose when bandwidth >1.3 MHz or unity-gain stability is mandatory, accepting 2× power penalty. |
Compared with TSV6295IPT, TSV6295IST sacrifices per-pair shutdown flexibility for smaller footprint, while TSV6395IPT trades 100% higher supply current for 85% bandwidth increase and unity-gain stability-making TSV6295IPT optimal for ultra-low-power, gain-constrained sensor interfaces.

FAQ
What is the minimum recommended gain for stable operation of TSV6295IPT?
The TSV6295IPT requires a minimum closed-loop gain of +4 in non-inverting configuration or −3 in inverting configuration to ensure ≥60° phase margin. This is due to internal compensation optimized for 1.3 MHz GBP at 29 µA. Using lower gains may cause oscillation, especially with capacitive loads >20 pF.
How does the dual shutdown functionality work on TSV6295IPT?
TSV6295IPT has two independent shutdown pins: SHDN1/2 (Pin 10) disables Amplifiers 1 and 2, while SHDN3/4 (Pin 12) disables Amplifiers 3 and 4. Pulling either pin to VCC− (logic low) places the corresponding amplifiers in high-impedance shutdown mode with 5 nA typical supply current per amp. Pins must never float.
Can TSV6295IPT operate from a 1.5 V supply?
Yes, TSV6295IPT is fully specified down to 1.5 V supply voltage. Key parameters-including 1.3 MHz GBP, 29 µA supply current, and rail-to-rail I/O-remain functional at 1.5 V, enabling direct use with single alkaline or NiMH cells without voltage regulation.
What package variants are available for the TSV6295 part number?
The TSV6295 is offered in TSSOP-14 (TSV6295IST), TSSOP-16 (TSV6295IPT), and SO-16 packages. Only the TSSOP-16 variant (IPT suffix) provides the full quad amplifier with dual independent shutdown pins; TSSOP-14 lacks SHDN3/4 and shares shutdown across all channels.
