Product details
Overview
TSV634IYPT from STMicroelectronics is a quad rail-to-rail input/output operational amplifier optimized for ultra-low-power, low-voltage operation (1.5 V to 5.5 V), delivering 880 kHz gain-bandwidth product at 60 µA per channel, 800 µV max input offset voltage (A-grade), and 1 pA typical input bias current - deployed in battery-powered sensor interfaces and portable medical instrumentation.
For engineers reviewing the TSV634IYPT datasheet, TSV634IYPT pinout, TSV634IYPT application, or TSV634IYPT equivalent, key selection criteria include shutdown current (5 nA typ), EMI rejection ratio (92 dB at 1.8 GHz), rail-to-rail output swing (≤35 mV from rails), and guaranteed stability with 100 pF capacitive loads - critical for precision analog front-ends in automotive and industrial edge nodes.
Technical Context
The TSV634IYPT implements dual complementary PMOS/NMOS input stages enabling true rail-to-rail input common-mode range (VCC− − 0.1 V to VCC+ + 0.1 V) without phase reversal, while its unity-gain-stable architecture supports stable operation with 100 pF capacitive loads in follower configurations.
It integrates a dedicated SHDN pin (VIH = 2 V, VIL = 0.8 V at VCC = 5 V) enabling fast turn-on/turn-off (200 ns / 20 ns), and features EMI-hardened design with 92 dB EMIRR at 1.8 GHz - validated across −40 °C to 125 °C operating temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - enables direct integration into single-cell Li-ion, coin-cell, and 3.3 V/5 V systems without level-shifting. |
| Quiescent Current (per channel) | 60 µA typ at 5 V - allows >1-year battery life in always-on wearable sensors drawing <100 µA total system current. |
| Gain Bandwidth Product | 880 kHz typ - supports anti-aliasing filtering up to ~140 kHz with ≥6 dB gain margin and 48° phase margin. |
| Input Offset Voltage (max) | 800 µV (A-grade) - ensures ≤0.016% full-scale error in 5 V-span 12-bit ADC front-ends without trimming. |
| Input Bias Current | 1 pA typ - preserves signal integrity in high-impedance pH, thermopile, or piezoelectric sensor interfaces. |
| EMI Rejection Ratio | 92 dB at 1.8 GHz - suppresses cellular band interference in portable diagnostic devices near RF transceivers. |
| Shutdown Current | 5 nA typ - reduces standby power by 12,000× vs active mode, critical for duty-cycled IoT endpoints. |
Pinout & Package
TSV634IYPT is housed in a MiniSO10 (SO-10) package - 3.0 mm × 4.4 mm, 1.75 mm height, exposed pad for thermal enhancement, RoHS-compliant ECOPACK®2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | Rail-to-rail sourcing/sinking (±40 mA) - drives 10 kΩ loads within 35 mV of supply rails. |
| 2 (IN− A) | Channel A inverting input | High-impedance node (1 pA bias) - requires guard ring layout to preserve CMRR >79 dB. |
| 3 (IN+ A) | Channel A non-inverting input | Common-mode range extends 0.1 V beyond rails - enables direct sensing of 0–5 V signals with single 5 V supply. |
| 4 (V−) | Negative supply | Ground reference for single-supply operation; connects to PCB ground plane via exposed pad. |
| 5 (SHDN) | Global shutdown control | Active-low logic input (VIL ≤ 0.8 V); must be hard-wired - floating state causes undefined output impedance. |
| 6 (IN+ B) | Channel B non-inverting input | Independent input stage - supports differential pair configuration with matched trace routing. |
| 7 (IN− B) | Channel B inverting input | Matched to Pin 2 - enables precise instrumentation amplifier topologies with external resistors. |
| 8 (OUT B) | Channel B output | Electrically isolated from OUT A - allows dual-path signal conditioning without crosstalk. |
| 9 (OUT C) | Channel C output | Third independent output - enables 3-channel sensor fusion (e.g., triaxial accelerometer interface). |
| 10 (OUT D) | Channel D output | Fourth output with identical specs - supports redundant monitoring or multi-stage filtering. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input & output | Enables full dynamic range utilization in 1.5 V–5.5 V systems - eliminates need for level-shifting or dual supplies. |
| EMI-hardened architecture | 92 dB rejection at 1.8 GHz - prevents RF rectification artifacts in cellular/Wi-Fi coexistence environments. |
| Guaranteed stability with 100 pF load | Eliminates external compensation components in unity-gain buffer designs - reduces BOM count and PCB area. |
| Ultra-low input bias current (1 pA) | Maintains accuracy in >1 GΩ source impedances - essential for electrochemical and photodiode front-ends. |
| Automotive-qualified (-40 °C to 125 °C) | Validated for under-hood and ADAS sensor modules - meets AEC-Q100 Grade 2 reliability requirements. |

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 |
|---|---|---|---|
| TSV634IST | Same silicon, MiniSO10 package but with different marking and tape/reel packaging - identical electrical specs and pinout. | No functional difference; selected for legacy procurement or alternate distribution channel compatibility. | Drop-in replacement if footprint and reel specs match - verify moisture sensitivity level (MSL) and reflow profile alignment. |
| MCP6004-E/SL | Higher quiescent current (100 µA), lower GBP (1 MHz), no shutdown mode, 2.7–5.5 V only - lacks EMI hardening and automotive temp range. | Suitable for cost-sensitive consumer electronics where RF immunity and extended temperature are not required. | Choose only for non-automotive, non-medical designs with >2.7 V supply and no need for sub-µA shutdown or 1.5 V operation. |
Compared with TSV634IYPT, TSV634IST offers identical performance in a functionally equivalent package, while MCP6004-E/SL trades ultra-low power and EMI robustness for higher speed and broader vendor availability - making it viable only in benign, fixed-supply environments.

FAQ
What is the maximum capacitive load the TSV634IYPT can drive without external compensation?
The TSV634IYPT is unity-gain stable with up to 100 pF capacitive load when configured as a voltage follower, as verified in the datasheet's AC performance tables and Figure 6. Driving larger loads (e.g., >200 pF) requires an isolation resistor (≥100 Ω) in series with the output to maintain phase margin above 45° - bench validation is mandatory for such cases.
Does the SHDN pin require a pull-up resistor, and what happens if left unconnected?
Yes - the SHDN pin must never float and requires a defined logic level: tie to VCC+ (≥2 V) to enable or to VCC− (≤0.8 V) to disable. Leaving it unconnected risks metastability, unpredictable output impedance, and potential shoot-through current in downstream circuitry - ST specifies mandatory hard-wiring per Section 4.4 of the datasheet.
How does the rail-to-rail input architecture affect common-mode rejection at supply extremes?
The dual complementary input stage transitions near (VCC+ − 0.7 V), causing a localized degradation in CMRR (to ~53 dB) and Vos (up to 2.2 mV) within ±100 mV of the positive rail - confirmed in Figures 16–17. For optimal CMRR (>79 dB), keep common-mode voltage ≥0.1 V below VCC+ and ≥0.1 V above VCC−.
Is the TSV634IYPT qualified for automotive applications, and which AEC-Q100 grade applies?
Yes - the TSV634IYPT is AEC-Q100 qualified for Grade 2 (−40 °C to +105 °C ambient, 125 °C junction), with full stress testing including HTOL, TC, and ESD per Rev 6 of the datasheet. It is approved for use in cabin electronics, body control modules, and ADAS auxiliary sensors - not for engine bay or safety-critical ASIL-B/C systems.
