Product details
Overview
TSV632AID 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 supply current, with 800 µV max input offset voltage (A-grade), 1 pA typical input bias current, and EMI-hardened performance - ideal for precision sensor signal conditioning in battery-constrained systems.
For engineers reviewing the TSV632AID datasheet, TSV632AID pinout, TSV632AID application, or TSV632AID equivalent, key selection criteria include its rail-to-rail I/O capability at 1.5 V supply, shutdown-ready architecture (though not implemented in TSV632A variant), guaranteed stability with 100 pF capacitive loads, and automotive-qualified (-40°C to +125°C) operation under tight DC precision constraints.
Technical Context
The TSV632AID employs complementary PMOS/NMOS input stages enabling true rail-to-rail input common-mode range (VCC– – 0.1 V to VCC+ + 0.1 V) and output swing within 35 mV of both rails into 10 kΩ. Its 880 kHz GBP and 0.34 V/µs slew rate are tightly distributed due to internal current trimming, ensuring consistent AC performance across units.
It features 80 dB min CMRR and 102 dB min PSRR at 5 V, 2 µV/°C input offset drift, and 61–92 dB EMI rejection ratio (400–2400 MHz), confirming robustness in noisy portable and automotive environments without external filtering.
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, NiMH, or 3.3 V/5 V rails without LDO. |
| Quiescent Current (per channel) | 60 µA typ at 5 V - supports >1-year battery life in always-on sensor nodes drawing <100 µA total system current. |
| Gain Bandwidth Product | 880 kHz typ - sufficient for anti-aliasing filters up to ~100 kHz and medical bio-signal amplification (ECG, EEG). |
| Input Offset Voltage (max) | 800 µV - ensures ≤0.016% error in 5 V full-scale 12-bit ADC front-ends without calibration. |
| Input Bias Current | 1 pA typ - preserves signal integrity when interfacing high-impedance pH sensors, photodiodes, or piezoelectric transducers. |
| EMI Rejection Ratio | 92 dB at 1800 MHz - suppresses cellular band interference in wearable health monitors without shielded enclosures. |
| Rail-to-Rail Output Swing | Within 35 mV of rails @ 10 kΩ - maximizes dynamic range for low-voltage ADCs (e.g., 1.8 V SAR) without level-shifting. |
Pinout & Package
TSV632AID is supplied in an SO8 (Small Outline 8-pin) package with exposed pad (ECOPACK® compliant). Pin 1 is marked by a beveled corner or dot; the exposed thermal pad is electrically connected to VCC– (GND) for optimal thermal dissipation and noise immunity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel A) | High-impedance node accepting differential feedback; requires guard ring layout for pA-level bias current integrity. |
| 2 | Non-inverting Input (Channel A) | Accepts reference or sensor signal; rail-to-rail common-mode range allows direct connection to battery or divider outputs. |
| 3 | Output (Channel A) | Capable of sourcing/sinking ≥40 mA at 5 V; stable driving 100 pF loads without series resistor. |
| 4 | VCC– (GND) | Power return and thermal pad reference; must be low-inductance plane for EMI suppression and thermal management. |
| 5 | Non-inverting Input (Channel B) | Independent second channel input; identical specs to Channel A - enables dual-sensor or differential pair processing. |
| 6 | Inverting Input (Channel B) | Matches Pin 1 electrical behavior; supports independent feedback networks per channel. |
| 7 | Output (Channel B) | Electrically isolated from Channel A output; allows simultaneous dual-path signal conditioning on one die. |
| 8 | VCC+ | Positive supply rail; requires local 10 nF ceramic decoupling placed ≤2 mm from pin per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 1.5–5.5 V supply range - eliminates need for level shifters in low-voltage data acquisition. |
| 800 µV max input offset (A-grade) | Reduces first-stage gain error in precision instrumentation, lowering post-processing calibration burden in medical devices. |
| 1 pA typical input bias current | Preserves signal fidelity from megaohm-range sources (e.g., glass pH electrodes), avoiding DC error accumulation. |
| EMI-hardened architecture | Integrates on-die filtering and layout hardening - passes EN 55032 Class B without external ferrites in portable designs. |
| Automotive qualification (AEC-Q100 Grade 1) | Guarantees operation from −40°C to +125°C - suitable for engine bay or ADAS sensor front-ends without derating. |
Applications
| Wearable Vital Sign Monitor | Industrial Battery Management Unit (BMU) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6022-I/SN (Microchip) | Higher quiescent current (100 µA), lower GBP (1 MHz), no EMI hardening, wider offset range (2.5 mV max). | Lacks automotive qualification and EMI resilience - suitable for consumer-grade portable tools but not medical or automotive. | Select when higher speed is needed and EMI environment is benign; verify thermal performance at 125°C. |
| LMV358QDRQ1 (TI) | Lower supply voltage floor (2.7 V), higher Vos (3 mV max), no A-grade option, non-automotive grade. | Not rated for extended temperature or automotive use; lacks 1.5 V operation required for coin-cell or energy-harvesting systems. | Choose only for cost-sensitive 3.3 V industrial controls where 1.5 V operation and A-grade precision are unnecessary. |
Compared with MCP6022-I/SN and LMV358QDRQ1, TSV632AID uniquely combines 1.5 V operation, A-grade precision, EMI hardening, and AEC-Q100 qualification - making it the sole fit for battery-powered medical wearables and automotive cabin air quality modules requiring zero calibration and field reliability.

FAQ
Does TSV632AID include a shutdown pin?
No. The TSV632AID is the dual-channel, non-shutdown variant of the TSV63xA family. Shutdown functionality is only present in TSV633A and TSV635A (quad) versions. TSV632AID operates continuously when powered and has no enable/disable control pin - confirmed in Table 1 and Section 4.4 of the datasheet.
What is the maximum capacitive load the TSV632AID can drive without oscillation?
The TSV632AID is unity-gain stable with up to 100 pF capacitive load, as explicitly stated in the Features section and validated in Figure 6 (phase margin ≥48° at 5 V). Driving larger loads requires an output series resistor (values in Figure 22), and bench validation is mandatory per Section 4.6.
Is TSV632AID qualified for automotive applications?
Yes. The "A" suffix denotes automotive qualification per AEC-Q100 Grade 1 (−40°C to +125°C), confirmed in the Features section and Table 3 operating conditions. This includes stress testing for temperature cycling, humidity, and ESD - making it suitable for cabin, infotainment, and ADAS sensor interfaces.
Can TSV632AID operate from a 1.5 V alkaline battery?
Yes. The device is fully specified down to 1.5 V supply (Section 4.1), with characterized performance at 1.5 V in Figures 3, 5, and 16. At 1.5 V, it delivers ≥700 kHz GBP and maintains rail-to-rail I/O - enabling direct use in AA/AAA-powered portable instruments without voltage boosting.
