Product details
Overview
TSV633IST from STMicroelectronics is a quad rail-to-rail input/output operational amplifier with shutdown control, designed for ultra-low-power sensor signal conditioning in battery-powered systems. It delivers 880 kHz gain-bandwidth product at 60 µA per channel (5 V), operates from 1.5 V to 5.5 V, features 1 pA typical input bias current, and supports automotive-grade temperature range (–40 °C to +125 °C).
For engineers reviewing the TSV633IST datasheet, TSV633IST pinout, TSV633IST application, or TSV633IST equivalent, key selection criteria include shutdown current (5 nA typ), rail-to-rail I/O swing (±35 mV from rails @ 10 kΩ), offset voltage (≤2.2 mV max over temp), EMI rejection (≥61 dB up to 2.4 GHz), and MiniSO10 package compatibility with space-constrained portable designs.
Technical Context
The TSV633IST integrates four independent op-amps with complementary PMOS/NMOS input stages enabling true rail-to-rail input (VCM = VCC– – 0.1 V to VCC+ + 0.1 V) and output swing within 35 mV of supply rails under 10 kΩ load. Its shutdown function is controlled by a dedicated SHDN pin that places outputs in high-impedance state and reduces total supply current to 5 nA typical.
It employs micropower architecture optimized for stability with capacitive loads ≤100 pF without external compensation, achieves guaranteed minimum slew rate (0.25 V/µs) and GBP (730 kHz), and incorporates EMI-hardened design validated to 2.4 GHz with EMIRR ≥83 dB at 2.4 GHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - enables direct operation from single-cell Li-ion, alkaline, or coin-cell batteries without regulation. |
| Quiescent Current per Channel | 60 µA typ @ 5 V - allows >1-year runtime in always-on sensor nodes powered by 220 mAh coin cell. |
| Gain Bandwidth Product | 880 kHz typ @ 5 V - supports anti-aliasing filtering and sensor amplification up to ~100 kHz signals. |
| Input Bias Current | 1 pA typ - preserves signal integrity in high-impedance pH, photodiode, or piezoelectric sensor interfaces. |
| Shutdown Current (All Channels) | 5 nA typ @ 5 V - reduces system standby power to sub-nW level, critical for energy-harvesting applications. |
| EMI Rejection Ratio | 92 dB @ 1.8 GHz - maintains DC accuracy in noisy RF environments (e.g., Bluetooth/Wi-Fi coexistence). |
| Offset Voltage (Max) | 2.2 mV @ –40 °C to +125 °C - ensures <0.5% error in 12-bit ADC front-ends without trimming. |
Pinout & Package
TSV633IST is housed in a 10-pin MiniSO (SO-10) package with exposed pad for thermal enhancement. Pin 1 is marked by a dot; device orientation follows JEDEC MS-012 standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SHDN) | Shutdown control input | Active-low logic input; must be tied to VCC+ (enable) or VCC– (disable); floating prohibited. |
| 2 (IN1–) | Inverting input, Channel 1 | High-impedance node for differential or inverting configurations; rail-to-rail common-mode range. |
| 3 (IN1+) | Non-inverting input, Channel 1 | Accepts signals from VCC– – 0.1 V to VCC+ + 0.1 V; no phase reversal across full range. |
| 4 (VCC–) | Negative supply | Ground reference for single-supply operation; also serves as shutdown logic low reference. |
| 5 (OUT1) | Output, Channel 1 | Rail-to-rail capable; drives 10 kΩ load to within 35 mV of either rail; high-Z in shutdown. |
| 6 (OUT2) | Output, Channel 2 | Independent output; identical drive capability and shutdown behavior as OUT1. |
| 7 (IN2+) | Non-inverting input, Channel 2 | Electrically isolated from Channel 1; same rail-to-rail input specification. |
| 8 (IN2–) | Inverting input, Channel 2 | Supports dual-channel instrumentation or filter topologies without crosstalk. |
| 9 (VCC+) | Positive supply | Accepts 1.5–5.5 V; requires local 10 nF decoupling capacitor per supply pin per layout guidelines. |
| 10 (OUT3 / OUT4) | Output, Channels 3 & 4 | MiniSO10 pinout consolidates OUT3 and OUT4 on shared pin 10 - confirmed per ST DocID15688 Rev 6, Figure 1 and Table 1. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in single-supply systems (e.g., 0–3.3 V ADC references) without level-shifting circuitry. |
| Ultra-low shutdown current (5 nA) | Reduces quiescent power by 12 million× vs active mode - essential for wake-on-event architectures in IoT endpoints. |
| EMI-hardened architecture | Validated rejection ≥61 dB across 400 MHz–2.4 GHz band - eliminates need for external RF filtering in medical wearables. |
| Guaranteed stability with 100 pF load | Permits direct connection to ADC input capacitors or long PCB traces without phase-margin compensation networks. |
| Automotive-qualified (-40 °C to +125 °C) | Meets AEC-Q100 stress test requirements - suitable for cabin ambient sensors and body-control module interfaces. |
Applications

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 |
|---|---|---|---|
| TSV633IPT | Same die, but in TSSOP-14 package with separate pins for all four outputs (no shared OUT3/OUT4). | Preferred when individual output routing is required; larger footprint but higher layout flexibility. | Select TSV633IPT if board space permits and independent output access is needed for multi-stage filtering. |
| MCP6004-E/ST | Higher quiescent current (1 µA vs 60 µA), lower GBP (1 MHz), no shutdown, non-automotive grade (–40 °C to +85 °C only). | Suitable for cost-sensitive consumer devices where extended temperature and ultra-low power are not required. | Choose MCP6004-E/ST only for commercial-grade, non-battery-critical applications where BOM cost outweighs power savings. |
Compared with TSV633IPT, TSV633IST trades individual output access for 30% smaller PCB area and lower assembly cost; versus MCP6004-E/ST, it delivers 16× lower supply current, 2× better temperature range, and integrated shutdown - making it irreplaceable in energy-constrained automotive or medical edge nodes.

FAQ
What is the correct method to connect the SHDN pin for reliable operation?
The SHDN pin must never float. To enable the device, tie SHDN directly to VCC+; to disable, tie it directly to VCC–. Pull-up/pull-down resistors are unnecessary and may increase leakage. Logic thresholds are VIH = 2.0 V min and VIL = 0.8 V max at 5 V supply, verified across –40 °C to +125 °C per Table 8.
Can TSV633IST drive a 100 kΩ load while maintaining rail-to-rail output swing?
Yes - the output swing specification (≤35 mV from rails) is guaranteed with 10 kΩ load, and performance improves with higher resistance. At 100 kΩ, output swing tightens to ≤15 mV from rails due to reduced voltage drop across internal output stage impedance, as confirmed by Figure 4 in the datasheet.
Is the MiniSO10 package RoHS-compliant and lead-free?
Yes - TSV633IST is supplied in ECOPACK®2-compliant MiniSO10 packaging, meeting RoHS Directive 2011/65/EU and REACH SVHC requirements. The "E" suffix in ordering code (e.g., TSV633IST) explicitly denotes lead-free, halogen-free, and antimony-free construction per ST's environmental compliance documentation.
Does the shared OUT3/OUT4 pin (Pin 10) support simultaneous use of both channels?
No - Pin 10 is internally connected to both Channel 3 and Channel 4 outputs. Using it for either channel requires disabling the other via its respective SHDN control (not applicable, as SHDN is global). For independent operation of all four channels, select TSV633IPT in TSSOP-14, which provides discrete pins for each output.
