Product details
Overview
TSV635AIPT from STMicroelectronics is a quad rail-to-rail input/output operational amplifier optimized for ultra-low-power, low-voltage systems. It delivers 880 kHz gain-bandwidth product at 60 µA per channel (5 V), supports 1.5–5.5 V supply, features 1 pA typical input bias current and 800 µV max offset voltage (A-grade), and includes independent shutdown control per amplifier - ideal for battery-powered sensor signal conditioning in automotive and portable medical devices.
For engineers reviewing the TSV635AIPT datasheet, TSV635AIPT pinout, TSV635AIPT application, or TSV635AIPT equivalent, key selection criteria include shutdown timing (200 ns turn-on), EMI rejection (92 dB at 1.8 GHz), rail-to-rail operation down to 1.5 V, and guaranteed stability with 100 pF capacitive loads - critical for precision analog front-ends in space-constrained embedded systems.
Technical Context
The TSV635AIPT implements dual complementary PMOS/NMOS input stages enabling true rail-to-rail input (VICM = VCC− − 0.1 V to VCC+ + 0.1 V) without phase reversal. Its shutdown logic is active-low on dedicated SHDN pins, placing outputs in high-impedance state with 5 nA typical quiescent current per channel.
AC performance is tightly controlled via internal current consumption trimming: GBP (730–880 kHz), slew rate (0.25–0.34 V/µs), and large-signal gain (89–98 dB) all exhibit narrow min/max spread. EMIRR reaches 92 dB at 1.8 GHz, confirming hardening against cellular-band interference.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - enables direct interface with Li-ion, coin-cell, and 3.3 V logic rails without level-shifting. |
| Quiescent Current / Channel | 60 µA typ at 5 V - supports >1-year battery life in always-on sensor nodes powered by CR2032 cells. |
| Gain Bandwidth Product | 880 kHz typ - sufficient for anti-aliasing filters up to ~100 kHz and DC-coupled biomedical signal amplification. |
| Input Offset Voltage (A-grade) | 800 µV max - ensures ≤0.016% error in 5 V full-scale 12-bit ADC interfaces without trimming. |
| Input Bias Current | 1 pA typ - preserves signal integrity in high-impedance pH, thermopile, or piezoelectric sensor circuits. |
| Shutdown Current (All Channels) | 5 nA typ at 5 V - reduces system standby power to nanoampere level for wake-on-event architectures. |
| EMI Rejection Ratio | 92 dB at 1.8 GHz - prevents RF rectification artifacts in cellular-connected wearables and telematics units. |
Pinout & Package
TSV635AIPT is supplied in a MiniSO10 (10-lead plastic micro package) with exposed pad for thermal enhancement. Pin numbering follows standard top-view convention with pin 1 marked by dot or notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amp A) | High-impedance node accepting differential signals; rail-to-rail common-mode range supports single-supply sensor biasing. |
| 2 | Non-inverting Input (Amp A) | Paired with Pin 1 for precision instrumentation configurations; 1 pA bias current minimizes resistor-induced errors. |
| 3 | Output (Amp A) | Capable of sourcing/sinking 40 mA at 5 V; rail-to-rail swing (≤35 mV from rails) enables full dynamic range utilization. |
| 4 | VCC− | Ground reference for dual-supply use or system ground in single-supply designs; connects to PCB ground plane via exposed pad. |
| 5 | SHDN A | Active-low enable for Amp A; must be tied to VCC− (not floating) to enter 5 nA shutdown mode with Hi-Z output. |
| 6 | Inverting Input (Amp B) | Independent channel input; identical specs to Amp A - allows dual-channel filtering or differential pair buffering. |
| 7 | Non-inverting Input (Amp B) | Matches Pin 2 performance; supports synchronous multi-channel acquisition in portable data loggers. |
| 8 | Output (Amp B) | Electrically isolated from Amp A output; enables independent load driving without crosstalk-induced settling errors. |
| 9 | SHDN B | Independent shutdown control for Amp B; permits dynamic channel gating in adaptive power management schemes. |
| 10 | VCC+ | Positive supply rail; requires local 10 nF ceramic decoupling per ST recommendation to maintain PSRR >75 dB. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full 0–5 V signal swing in single-supply 5 V systems, eliminating level-shifting components in sensor interfaces. |
| Ultra-low input bias current (1 pA) | Preserves accuracy in >100 MΩ source impedances - essential for electrochemical sensors and photodiode transimpedance stages. |
| EMI-hardened architecture | Rejects 1.8 GHz cellular noise at 92 dB, preventing false triggers in automotive cabin controllers and wireless health monitors. |
| Guaranteed stability with 100 pF load | Eliminates need for external compensation in unity-gain buffer applications, reducing BOM count and PCB area. |
| Independent per-amplifier shutdown | Allows selective channel disabling in quad configurations - e.g., powering only active sensor channels in multi-parameter wearables. |
Applications
| Portable ECG Monitor | Automotive Cabin Air Quality Sensor |

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 |
|---|---|---|---|
| TSV635IST | Same die, MiniSO10 package without ECOPACK® RoHS exemption - identical electrical specs and pinout. | No difference; both qualified for automotive (-40°C to 125°C) and support same shutdown timing and EMI rejection. | Select TSV635AIPT for lead-free compliance with full ECOPACK® documentation; choose TSV635IST if legacy exemption requirements apply. |
| MCP6004-E/ST | Higher 100 µA ICC, lower 1 MHz GBP, no shutdown function, 2 mV Vos max - wider offset and no power-gating capability. | Lacks per-channel shutdown and EMI hardening; unsuitable for RF-noisy environments or ultra-low-power wake-on-event systems. | Use only where cost is primary constraint and 5 nA shutdown current or 92 dB EMIRR are not required. |
Compared with TSV635AIPT, TSV635IST offers identical performance with alternate environmental compliance, while MCP6004-E/ST trades off shutdown, EMI immunity, and offset precision for broader distributor availability - making TSV635AIPT the sole choice for automotive-grade, RF-resilient, battery-optimized quad amplification.

FAQ
What is the maximum capacitive load the TSV635AIPT can drive without external compensation?
The TSV635AIPT is unity-gain stable with up to 100 pF capacitive load at its output, as verified in the datasheet's AC characterization (Table 7, Figure 6). Driving larger loads requires a series resistor (e.g., 10–100 Ω) between the output and capacitor to restore phase margin - values are detailed in Figure 22 of the application note. This eliminates need for complex compensation networks in most portable sensor buffer designs.
Does the TSV635AIPT support true rail-to-rail input at 1.5 V supply?
Yes - the input common-mode range extends from VCC− − 0.1 V to VCC+ + 0.1 V across the full 1.5–5.5 V supply range, confirmed in Table 3 (VICM specification) and Figure 16/17. At 1.5 V, this provides −0.1 V to +1.6 V input coverage, enabling direct interfacing with 0–1.5 V sensor outputs without level-shifting circuitry.
How does the shutdown function affect output impedance and leakage?
When SHDN is pulled low, each amplifier's output enters high-impedance state with ≤1 nA leakage current (Table 8, IOLeak) over −40°C to 125°C. This allows safe multiplexing of multiple TSV635AIPT outputs onto shared traces without interaction, and prevents loading of downstream ADC inputs during sleep cycles - critical for low-power data acquisition systems.
Is the TSV635AIPT qualified for automotive applications?
Yes - the "A" suffix denotes automotive qualification per AEC-Q100 Grade 1 (−40°C to +125°C ambient), with full characterization across temperature and supply voltage extremes. The device also meets stringent EMI immunity requirements (EMIRR ≥92 dB at 1.8 GHz), making it suitable for cabin control units, ADAS sensor interfaces, and body electronics where RF noise is prevalent.
