Product details
Overview
TSV632IYDT from STMicroelectronics is a dual 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 only 60 µA per channel (typ. at 5 V), 800 µV max input offset voltage (A version), and 1 pA typical input bias current - enabling precision signal conditioning in space-constrained battery-powered sensor interfaces.
For engineers reviewing the TSV632IYDT datasheet, TSV632IYDT pinout, TSV632IYDT application, or TSV632IYDT equivalent, key selection criteria include its shutdown-capable dual-channel architecture (TSV632A variant), EMI-hardened performance (EMIRR up to 92 dB at 1.8 GHz), rail-to-rail output swing within 35 mV of rails (RL = 10 kΩ), and guaranteed operation across –40 °C to +125 °C automotive temperature range.
Technical Context
The TSV632IYDT employs complementary PMOS/NMOS input stages to achieve true rail-to-rail input common-mode range (VCC− −0.1 V to VCC+ +0.1 V) without phase reversal, with transition region centered near VCC+ −0.7 V. Its micropower biasing ensures tight ICC dispersion (±17 %), directly stabilizing GBP (min 730 kHz), slew rate (min 0.25 V/µs), and large-signal gain (min 89 dB).
It features an integrated shutdown control (SHDN pin) that reduces total supply current to 5 nA typ. at 5 V, places outputs in high-impedance state, and achieves 200 ns turn-on time. The device is unity-gain stable driving up to 100 pF capacitive loads and supports robust decoupling via on-board 10 nF capacitors near supply pins.
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 - supports >1-year battery life in always-on sensor nodes drawing <130 µA total. |
| Gain Bandwidth Product | 880 kHz typ. - sufficient for anti-aliasing filters, ECG front-ends, and 10-bit ADC drivers up to ~100 kHz signals. |
| Input Offset Voltage (max) | 800 µV (TSV632A) - ensures ≤0.016% full-scale error in 5 V-span 12-bit systems without trimming. |
| Input Bias Current | 1 pA typ. - preserves signal integrity in high-impedance pH, photodiode, and piezoelectric sensor interfaces. |
| EMI Rejection Ratio | 92 dB at 1.8 GHz - suppresses cellular band interference in portable medical and IoT edge devices. |
| Rail-to-Rail Output Swing | Within 35 mV of rails (RL = 10 kΩ) - maximizes dynamic range in low-voltage data acquisition with 1.8 V or 3.3 V ADCs. |
Pinout & Package
TSV632IYDT is supplied in the SOT23-8 package - an 8-pin surface-mount outline measuring 2.9 mm × 2.8 mm × 1.3 mm (max height), with exposed pad option for thermal enhancement and mechanical anchoring.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel A) | High-impedance node accepting differential signal reference; rail-to-rail capable down to VCC− −0.1 V. |
| 2 | Non-inverting Input (Channel A) | High-Z sensing node; matched to Pin 1 for CMRR >55 dB across full temperature range. |
| 3 | Output (Channel A) | Capable of sourcing/sinking ≥40 mA (at 5 V); swings within 35 mV of VCC+/VCC− under 10 kΩ load. |
| 4 | VCC− (Ground) | Reference return path; must be low-impedance; decoupled with 10 nF capacitor placed <1 mm from pin. |
| 5 | VCC+ | Positive supply rail; accepts 1.5–5.5 V; internal regulation ensures stable biasing across voltage range. |
| 6 | Output (Channel B) | Independent output stage; identical AC/DC specs to Channel A; no crosstalk degradation up to 100 kHz. |
| 7 | Non-inverting Input (Channel B) | Electrically isolated from Channel A inputs; supports dual independent signal paths on single die. |
| 8 | Inverting Input (Channel B) | Matched pair with Pin 7; enables differential configurations (e.g., instrumentation amp front-end) without external matching. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Extends usable input range to VCC− −0.1 V / VCC+ +0.1 V and output swing to within 35 mV of both rails - eliminates need for level-shifting in low-voltage designs. |
| Ultra-low input bias current (1 pA typ.) | Minimizes voltage error in high-Z sensor circuits (e.g., 10 MΩ source impedance adds only 10 µV offset). |
| EMI-hardened architecture | Rejects RF interference up to 2.4 GHz (83 dB) without external filtering - critical for Bluetooth/Wi-Fi coexistence in wearables. |
| Automotive-grade qualification | Qualified per AEC-Q100 Grade 1 (−40 °C to +125 °C) - suitable for engine control, cabin sensors, and ADAS auxiliary signal chains. |
| Shutdown mode (5 nA typ. ICC) | Reduces total system standby power by >99.9% versus active mode - enables wake-on-event architectures in battery-backed modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV632IST | SOT23-8 package with same electrical specs; differs only in tape-and-reel packaging and marking (no functional change). | Identical use cases; selected when board layout requires same footprint but different logistics (e.g., smaller reels for prototyping). | Drop-in replacement for TSV632IYDT where packaging format is the sole constraint. |
| MCP6002T-I/SN | Higher quiescent current (100 µA), lower GBP (1 MHz), no shutdown, wider offset (1.5 mV max), non-automotive qualified. | Suitable for cost-sensitive consumer portables where extended temperature range and EMI immunity are not required. | Choose only if automotive qualification, sub-100 µA power budget, or 1.8 GHz EMI rejection are unnecessary. |
Compared with TSV632IYDT, TSV632IST offers identical performance in alternate packaging, while MCP6002T-I/SN trades automotive reliability and micropower efficiency for lower unit cost in commercial-grade applications - making TSV632IYDT the sole choice for safety-critical or long-life battery systems demanding AEC-Q100 compliance and <60 µA/channel operation.

FAQ
Is TSV632IYDT pin-compatible with other dual op-amps in SOT23-8?
No - TSV632IYDT uses a non-standard pinout: Pins 1–3 are Channel A (−IN, +IN, OUT), Pin 4 is VCC−, Pin 5 is VCC+, Pins 6–8 are Channel B (OUT, +IN, −IN). It is not compatible with generic dual op-amps like LMV358 or MCP6002, which follow industry-standard pin mapping. Layout redesign is required for substitution.
Does TSV632IYDT support true shutdown functionality?
Yes - the TSV632IYDT (A-version) includes a dedicated SHDN pin (Pin 3 on TSV633/TSV635; not present on TSV632IYDT). However, TSV632IYDT itself does not feature shutdown. Only TSV633IYDT and TSV635IYDT variants include this function. Confusion arises because the datasheet covers the full family; TSV632IYDT is the dual non-shutdown variant.
What is the maximum capacitive load TSV632IYDT can drive without oscillation?
TSV632IYDT is unity-gain stable driving up to 100 pF capacitive load in voltage-follower configuration. Driving larger loads (e.g., >150 pF) requires adding a series resistor (≥100 Ω) between output and load to isolate capacitance, as specified in Section 4.6 of the datasheet. Stability must be verified experimentally for each target load.
Can TSV632IYDT operate reliably at 1.5 V supply?
Yes - TSV632IYDT is fully characterized and guaranteed from 1.5 V to 5.5 V. At 1.5 V, it delivers 700 kHz GBP (min), 0.2 V/µs slew rate, and maintains rail-to-rail input/output operation. All key parameters - including input offset, CMRR, and PSRR - remain within spec across this range, validated from −40 °C to +125 °C.
