Product details
Overview
TSV632ILT 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 60 µA supply current per channel, 800 µV max input offset voltage (A version), 1 pA typical input bias current, and EMI-hardened performance - ideal for precision sensor front-ends in battery-constrained medical and portable instrumentation.
For engineers reviewing the TSV632ILT datasheet, TSV632ILT pinout, TSV632ILT application, or TSV632ILT equivalent, key selection criteria include its shutdown-capable dual-channel architecture (though TSV632ILT itself lacks SHDN), guaranteed rail-to-rail I/O swing down to 35 mV from rails, stable operation with 100 pF capacitive loads, and automotive-grade qualification (-40 °C to +125 °C).
Technical Context
The TSV632ILT employs 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 output stage delivers ±40 mA drive capability into resistive loads and maintains stability up to 100 pF without external compensation. Its 0.25 V/µs min slew rate and 730 kHz min GBP are tightly distributed due to internal current trimming.
EMI rejection is hardened across 400–2400 MHz (61–92 dB EMIRR), and DC precision is enhanced by <2 µV/°C offset drift and 80 dB min CMRR at 5 V. It operates fully specified at 1.8 V, 3.3 V, and 5 V, with supply current varying only ±17% across process/voltage/temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - enables direct integration with single-cell Li-ion, NiMH, or 3.3 V/5 V logic rails without level-shifting. |
| Quiescent Current (per channel) | 60 µA typ at 5 V - supports multi-year battery life in always-on wearable sensors and IoT endpoints. |
| Gain Bandwidth Product | 880 kHz typ - sufficient for anti-aliasing filters, ECG amplification, and low-frequency transducer signal conditioning. |
| Input Offset Voltage (max) | 800 µV (TSV632A variant) - ensures ≤0.8 mV error in 1 V full-scale 12-bit ADC interfaces without trimming. |
| Input Bias Current | 1 pA typ - preserves signal integrity in high-impedance pH, photodiode, or piezoelectric sensor nodes. |
| Output Swing (RL = 10 kΩ) | Within 35 mV of rails - maximizes dynamic range in low-voltage data acquisition systems. |
| EMI Rejection Ratio | 92 dB at 1800 MHz - suppresses cellular band interference in handheld medical devices. |
Pinout & Package
TSV632ILT is supplied in an 8-pin SOT23-8 package (JEDEC MO-178AA), with exposed pad not connected internally. Pin 1 is marked by a dot; device orientation follows standard SOT23-8 top view labeling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel A) | High-impedance node accepting differential signals; rail-to-rail common-mode range supports ground-referenced inputs. |
| 2 | Non-inverting Input (Channel A) | Paired with Pin 1 for differential gain configuration; matched input structure minimizes offset mismatch. |
| 3 | Output (Channel A) | Capable of sourcing/sinking ≥40 mA; rail-to-rail swing enables full utilization of ADC reference range. |
| 4 | VCC– (GND) | Power return path; requires local 10 nF decoupling to minimize PSRR degradation and oscillation risk. |
| 5 | VCC+ | Positive supply input; accepts 1.5–5.5 V; internal regulation ensures stable biasing across voltage range. |
| 6 | Output (Channel B) | Independent output stage; no crosstalk with Channel A above −80 dB at 10 kHz. |
| 7 | Non-inverting Input (Channel B) | Electrically identical to Pin 2; supports dual-sensor synchronous sampling architectures. |
| 8 | Inverting Input (Channel B) | Matched to Pin 1; enables dual-opamp configurations like instrumentation amps or dual-filter stages. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full-scale signal handling from 0 V to VCC in single-supply systems, eliminating level-shifting circuitry. |
| 1 pA typical input bias current | Reduces leakage-induced errors in >100 MΩ sensor interfaces (e.g., electrochemical gas sensors). |
| EMI-hardened architecture | Guarantees stable operation in noisy RF environments (e.g., Bluetooth/Wi-Fi coexistence in portable diagnostics). |
| Automotive qualification (AEC-Q100 Grade 1) | Validated for −40 °C to +125 °C operation - suitable for under-hood or cabin-mounted industrial controllers. |
| Unity-gain stable with 100 pF load | Eliminates need for external isolation resistors in capacitive sensor readouts (e.g., touch, humidity, proximity). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6002-E/SN | Lower GBP (1 MHz), higher Iq (100 µA), no automotive qualification, 2.7–5.5 V supply only. | Lacks EMI hardening and extended temp support; suited for consumer-grade portable devices only. | Choose when cost sensitivity outweighs automotive reliability and RF immunity requirements. |
| LMV358IDR | Higher Iq (150 µA), wider VCC (2.7–5.5 V), no 1.5 V operation, lower EMIRR (<50 dB), no AEC-Q100. | Not viable for sub-2 V battery systems or harsh EMI environments; limited to commercial-temp industrial controls. | Select only if legacy design reuse or distributor stock availability dictates compatibility with existing LMV358 layouts. |
Compared with MCP6002-E/SN and LMV358IDR, TSV632ILT uniquely combines 1.5 V operation, automotive qualification, and industry-leading EMI rejection - making it the sole choice for safety-critical, battery-operated medical and automotive-adjacent sensing.

FAQ
Is TSV632ILT pin-compatible with TSV632A?
Yes - TSV632ILT and TSV632A share identical SOT23-8 pinout, electrical specifications, and package dimensions. The 'A' suffix denotes tighter input offset voltage (800 µV max vs. 3 mV max for non-A), but all other parameters including supply current, GBP, and rail-to-rail behavior are functionally identical and interchangeable in layout.
Does TSV632ILT support shutdown mode?
No - TSV632ILT is the base dual op-amp variant without shutdown functionality. Shutdown is only available on TSV633/TSV633A (dual with SHDN) and TSV635/TSV635A (quad with SHDN). TSV632ILT draws 60 µA continuously per channel and has no dedicated SHDN pin.
Can TSV632ILT drive a 100 kΩ load at 5 V supply?
Yes - TSV632ILT maintains rail-to-rail output swing and <0.002% THD+noise when driving 100 kΩ loads at 5 V supply and 1 kHz, as verified in Table 7 and Figure 12 of the datasheet. Its 40 mA output drive capability far exceeds the 50 µA required for this load.
What decoupling capacitance is recommended for TSV632ILT?
A 10 nF ceramic capacitor placed as close as possible to Pins 4 (VCC–) and 5 (VCC+) is mandatory per Section 4.7 of the datasheet. This minimizes supply impedance at high frequencies, ensuring PSRR >75 dB and preventing instability induced by PCB trace inductance.
