Product details
Overview
TSV625IPT from STMicroelectronics is a quad rail-to-rail input/output CMOS operational amplifier in TSSOP-16 package, delivering 420 kHz gain bandwidth at 29 µA supply current per amplifier, 1.5–5.5 V operation, and ultra-low 1 pA input bias current-designed for low-power sensor signal conditioning in portable medical devices.
For engineers reviewing the TSV625IPT datasheet, TSV625IPT pinout, TSV625IPT application, or TSV625IPT equivalent, key selection criteria include shutdown control timing (200 ns turn-on), rail-to-rail output swing (≤35 mV from rails), EMI hardening (92 dB at 1.8 GHz), and guaranteed unity-gain stability with 100 pF capacitive loads.
Technical Context
The TSV625IPT integrates four independent op-amps with complementary PMOS/NMOS input stages enabling rail-to-rail input common-mode range (VCC− −0.1 V to VCC+ +0.1 V) and rail-to-rail output swing into 10 kΩ loads. Its architecture supports stable operation across −40 °C to +125 °C with no phase reversal.
Two dedicated shutdown pins (SHDN1/2 and SHDN3/4) independently disable amplifier pairs, reducing total quiescent current to 5 nA typ per disabled channel. The device uses internal current trimming to minimize parameter spread-ensuring GBP ≥350 kHz and slew rate ≥0.12 V/µs across voltage and temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 1.5–5.5 V: Enables direct use with single-cell Li-ion (3.0–4.2 V), coin cell (1.5 V), or 3.3/5 V logic rails without level-shifting. |
| Gain bandwidth product | 420 kHz typ at 5 V: Supports anti-aliasing filtering up to ~66 kHz in unity-gain configuration with <1% gain error. |
| Supply current per op-amp | 29 µA typ at 5 V: Allows 4-channel operation at <116 µA total, extending battery life in always-on wearable sensors. |
| Input bias current | 1 pA typ: Minimizes voltage error in high-impedance pH or photodiode front-ends (>1 GΩ source impedance). |
| Input offset voltage | 800 µV max (A version): Ensures ≤0.8 mV DC error in 12-bit ADC driver applications with 2.5 V reference. |
| Shutdown current | 5 nA typ per channel: Reduces system standby power by >99.9% when amplifiers are inactive between sensor readings. |
| EMI rejection ratio | 92 dB at 1.8 GHz: Maintains signal integrity in cellular-connected medical monitors exposed to LTE/5G RF fields. |
Pinout & Package
TSSOP-16 package: 5.0 mm × 4.4 mm × 1.05 mm body, 0.65 mm pitch, lead-free and RoHS-compliant ECOPACK®2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7 | Inverting input (−) | Differential input node for each of four op-amps; accepts signals from VCC− −0.1 V to VCC+ +0.1 V. |
| 2, 4, 6, 8 | Non-inverting input (+) | Differential input node for each op-amp; matched to inverting inputs for common-mode rejection. |
| 9, 11, 13, 15 | Output | Rail-to-rail output capable of sourcing/sinking ≥40 mA at 5 V; settles within 200 ns after shutdown release. |
| 10, 12 | SHDN1/2, SHDN3/4 | Active-high digital control lines: Pull to VCC+ to enable respective amplifier pair; must not float. |
| 14 | VCC+ | Positive supply rail (1.5–5.5 V); requires local 10 nF decoupling capacitor per datasheet layout guidance. |
| 16 | VCC− | Negative supply rail (typically ground); serves as reference for all inputs, outputs, and shutdown logic. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode extends 0.1 V beyond rails; output swings within 35 mV of VCC+/VCC− into 10 kΩ load-enabling full dynamic range utilization in low-voltage systems. |
| Ultra-low power shutdown | 5 nA typ per channel shutdown current allows multi-second sleep intervals without measurable battery drain in intermittent-sampling architectures. |
| Unity-gain stable | Stable with up to 100 pF capacitive load without external compensation-simplifies design of buffered sensor interfaces and active filters. |
| EMI hardened | 92 dB rejection at 1.8 GHz prevents RF rectification-induced DC offset shifts in cellular/Wi-Fi co-located medical devices. |
| Guaranteed AC performance | Minimum 350 kHz GBP and 0.12 V/µs slew rate across temperature and supply ensure predictable bandwidth in production units. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV625AIPR | Same die, A-grade (800 µV max Vio vs. 1 mV for standard TSV625); identical pinout and specs otherwise. | Better DC accuracy required for precision medical diagnostics where offset drift impacts long-term calibration stability. | Select TSV625AIPR when input offset voltage ≤800 µV is mandatory across temperature; same footprint and supply behavior. |
| MCP6004-E/ST | Higher supply current (1 µA vs. 29 µA), lower GBP (1 MHz), no shutdown pins, SO-14 package only. | Suitable for cost-sensitive industrial controls where power is not constrained and shutdown is unnecessary. | Choose MCP6004-E/ST only if 1 µA supply is acceptable and dual shutdown control is not needed-no pin compatibility. |
Compared with TSV625IPT, TSV625AIPR offers tighter DC accuracy without trade-offs in power or features, while MCP6004-E/ST sacrifices shutdown capability and ultra-low power for higher speed and lower cost in non-battery applications.

FAQ
What is the maximum capacitive load the TSV625IPT can drive without external compensation?
The TSV625IPT is unity-gain stable with capacitive loads up to 100 pF, as verified in the datasheet under "Driving resistive and capacitive loads." For loads exceeding 100 pF, a series resistor (e.g., 10–100 Ω) at the output is recommended to maintain phase margin above 40°, and bench validation is required per Figure 22 guidelines.
How does the shutdown function affect output state and leakage?
When SHDN1/2 or SHDN3/4 is pulled low (to VCC−), the corresponding amplifier pair enters high-impedance output state with ≤1 nA output leakage (typ) at 125 °C. Output remains floating-not clamped-so external pull-downs may be needed in high-impedance systems to prevent noise coupling.
Can the TSV625IPT operate from a 1.5 V supply while maintaining full AC performance?
Yes: the TSV625IPT is fully specified down to 1.5 V, with guaranteed minimum GBP of 275 kHz and slew rate of 0.1 V/µs at that voltage. Performance degrades linearly with supply-e.g., GBP drops from 420 kHz at 5 V to 350 kHz at 3.3 V and 275 kHz at 1.5 V-but remains functional across the entire 1.5–5.5 V range.
Is the TSV625IPT pin-compatible with other TSSOP-16 quad op-amps like the LM324 or TLV2464?
No: the TSV625IPT uses a proprietary pinout optimized for dual-pair shutdown control (SHDN1/2 on pins 10/12), differing from industry-standard layouts. LM324 and TLV2464 assign pins 1/7/10/13 to outputs and lack dedicated shutdown terminals-making direct replacement impossible without PCB redesign.
