Product details
Overview
TSV625AIPT from STMicroelectronics is a quad rail-to-rail input/output CMOS operational amplifier optimized for ultra-low-power, low-voltage operation in battery-powered systems. It delivers 420 kHz gain bandwidth at 29 µA supply current per amplifier, supports 1.5–5.5 V supply, and features 800 µV max input offset voltage (A-grade), 1 pA typical input bias current, and 5 nA shutdown current - enabling precision signal conditioning in portable medical sensors and handheld instrumentation.
For engineers reviewing the TSV625AIPT datasheet, TSV625AIPT pinout, TSV625AIPT application, or TSV625AIPT equivalent, key selection criteria include its guaranteed unity-gain stability with 100 pF capacitive loads, EMI-hardened performance (92 dB EMIRR at 1.8 GHz), shutdown control logic compatibility (VIH = 2 V, VIL = 0.8 V at 5 V), and MiniSO10 package footprint constraints for space-constrained PCB layouts.
Technical Context
The TSV625AIPT employs complementary PMOS/NMOS input stages to achieve rail-to-rail input common-mode range (VCC− −0.1 V to VCC+ +0.1 V) and rail-to-rail output swing (within 35 mV of rails into 10 kΩ). Its architecture ensures no phase reversal across the full input range and maintains stable DC accuracy (ΔVio/ΔT = 2 µV/°C) over −40 °C to +125 °C.
It integrates two independent shutdown pins (SHDN1/2 and SHDN3/4) that place each pair of amplifiers into high-impedance state with 5 nA typ ICC in shutdown mode. Turn-on/off times are 200 ns and 20 ns respectively, supporting rapid power cycling in duty-cycled sensor front-ends without compromising settling behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.5–5.5 V - enables direct integration with single-cell Li-ion, alkaline, or coin-cell batteries without regulation. |
| Quiescent Current | 29 µA typ per op-amp - allows >1-year runtime on 220 mAh coin cell powering four channels continuously. |
| Gain Bandwidth | 420 kHz typ - sufficient for anti-aliasing filters, sensor amplification, and active low-pass filtering up to ~40 kHz. |
| Input Offset Voltage | 800 µV max (A version) - supports 12-bit ADC interfacing with ≤0.2% gain error in uncalibrated systems. |
| Input Bias Current | 1 pA typ - preserves signal integrity in high-impedance pH, photodiode, or piezoelectric sensor interfaces. |
| EMI Rejection Ratio | 92 dB at 1.8 GHz - mitigates cellular/WiFi interference in wearable medical devices without external shielding. |
| Shutdown Current | 5 nA typ - reduces total system standby power to sub-20 nA when all four amplifiers are disabled. |
Pinout & Package
TSV625AIPT is housed in a 10-pin MiniSO package (3.0 × 4.9 mm, 0.5 mm pitch), optimized for compact, thermally efficient layouts in portable equipment. Pin numbering follows standard top-view orientation with pin 1 marked by a dot or bevel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | In1+ | Non-inverting input of amplifier 1 - accepts signals up to VCC+ +0.1 V, compatible with rail-to-rail sensor outputs. |
| 2 | In1− | Inverting input of amplifier 1 - matched to In1+ for <2 µV/°C drift and minimal common-mode error. |
| 3 | Out1 | Output of amplifier 1 - drives 10 kΩ load within 35 mV of rails; stable with ≤100 pF capacitive load. |
| 4 | VCC+ | Positive supply rail - requires local 10 nF decoupling capacitor placed within 2 mm for EMI immunity. |
| 5 | In2+ | Non-inverting input of amplifier 2 - electrically isolated from In1±; shares same input stage topology. |
| 6 | In2− | Inverting input of amplifier 2 - supports differential configurations with matched offset and CMRR ≥74 dB. |
| 7 | Out2 | Output of amplifier 2 - independently buffered; no crosstalk observed (<−100 dB) at 1 kHz between channels. |
| 8 | SHDN1/2 | Shutdown control for amplifiers 1 & 2 - logic-high (>2 V) enables, logic-low (<0.8 V) disables both with 200 ns turn-on. |
| 9 | VCC− | Negative supply rail (ground reference) - must be connected directly to PCB ground plane with low-inductance path. |
| 10 | SHDN3/4 | Shutdown control for amplifiers 3 & 4 - independent of SHDN1/2, enabling asymmetric power gating per channel pair. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input range extends 0.1 V beyond rails; output swings to within 35 mV of VCC+/VCC− - maximizes dynamic range in 1.8 V systems. |
| Unity-gain stability | Guaranteed stable with 100 pF capacitive load - eliminates need for external compensation in sensor buffer applications. |
| EMI hardening | 92 dB rejection at 1.8 GHz - prevents RF rectification artifacts in ECG/EEG front-ends operating near cellular bands. |
| Low-offset A-grade | 800 µV max Vio over temperature - enables DC-coupled transducer signal chains without trimming or calibration. |
| Dual independent shutdown | Two SHDN pins control two amplifier pairs separately - supports adaptive power management in multi-sensor nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6004-E/ST | Higher 100 µA supply current, 1 MHz GBW, no shutdown pins, SOIC-14 package (larger footprint). | Lacks independent shutdown; unsuitable for duty-cycled sensor nodes requiring sub-µA standby. | Select when higher speed is required and board area permits SOIC-14; avoid where MiniSO10 footprint or nanoamp shutdown is mandatory. |
| TSV625IST | Same quad MiniSO10 package and pinout, but non-A grade (2.2 mV max Vio), no guaranteed 800 µV offset spec. | Acceptable for AC-coupled or calibrated systems; insufficient for DC-coupled medical sensors needing <1 mV offset. | Choose for cost-sensitive industrial monitoring where offset drift is compensated in firmware; not for certified medical analog front-ends. |
Compared with MCP6004-E/ST, TSV625AIPT reduces supply current by 71% and adds dual shutdown control in 40% smaller area; versus TSV625IST, it guarantees tighter offset for uncalibrated DC measurements while retaining identical layout and thermal profile.

FAQ
What is the maximum capacitive load the TSV625AIPT can drive without external compensation?
The TSV625AIPT is unity-gain stable with capacitive loads up to 100 pF, as verified in the datasheet under "Driving resistive and capacitive loads" (Section 4.6). Driving larger loads requires a series resistor (e.g., 10–100 Ω) at the output, with final stability confirmed via bench testing and SPICE simulation using ST's provided macromodel.
How does the shutdown function behave across temperature and supply voltage?
Shutdown current remains ≤1.5 µA over −40 °C to +125 °C and 1.5–5.5 V supply, per Table 8. Logic thresholds are VIH ≥ 2 V and VIL ≤ 0.8 V at 5 V, scaling linearly down to VIH ≥ 1.35 V at 1.8 V. Output enters high-impedance state within 20 ns, with leakage <1 nA at 125 °C.
Can TSV625AIPT operate from a single 1.5 V alkaline cell?
Yes - the device is fully specified from 1.5 V, with tested performance including 29 µA supply current, 350 kHz GBP, and rail-to-rail I/O at 1.5 V. Input common-mode range extends to (VCC−) −0.1 V, enabling direct interface with grounded sensors even at end-of-life battery voltage (~0.9 V).
Is the MiniSO10 package RoHS-compliant and halogen-free?
Yes - TSV625AIPT is offered in ECOPACK®2-compliant MiniSO10 packaging, meeting RoHS Directive 2011/65/EU and halogen-free requirements per IEC 61249-2-21. Full material declarations and compliance documentation are available on STMicroelectronics' official product page.
