Product details
Overview
TSV622ILT from STMicroelectronics is a dual rail-to-rail input/output CMOS operational amplifier optimized for ultra-low-power, low-voltage operation (1.5–5.5 V), delivering 420 kHz gain bandwidth at 29 µA supply current per amplifier, 800 µV max input offset voltage (A version), and unity-gain stability with up to 100 pF capacitive load - deployed in portable medical sensors and battery-powered signal conditioning circuits.
For engineers reviewing the TSV622ILT datasheet, TSV622ILT pinout, TSV622ILT application, or TSV622ILT equivalent, key selection criteria include its 29 µA quiescent current, rail-to-rail I/O swing within 35 mV of rails, shutdown capability (5 nA typ), EMI-hardened architecture (EMIRR up to 92 dB at 1.8 GHz), and guaranteed performance across –40 °C to +125 °C.
Technical Context
The TSV622ILT implements 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 drives within 35 mV of both supply rails under 10 kΩ load. Its internal current-starved compensation ensures unity-gain stability with ≤100 pF capacitive loads.
It features an EMI-hardened design validated to 4 kV HBM ESD, 1.5 kV CDM, and EMIRR of 92 dB at 1.8 GHz - critical for noisy industrial or portable RF-adjacent environments. The device operates down to 1.5 V, with DC parameters (Vio, CMRR, PSRR) fully characterized at 1.8 V, 3.3 V, and 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - enables direct use with single-cell Li-ion, NiMH, or coin-cell batteries without regulation. |
| Quiescent Current per Amp | 29 µA typ (5 V) - supports >1-year battery life in always-on sensor nodes drawing <100 µA total system current. |
| Gain Bandwidth Product | 420 kHz typ (5 V) - sufficient for DC–200 Hz biomedical signal amplification and anti-aliasing filtering. |
| Input Offset Voltage | 800 µV max (TSV622A variant) - ensures ≤0.8 mV error in 1 V full-scale instrumentation front-ends. |
| Input Bias Current | 1 pA typ - preserves signal integrity in high-impedance pH, photodiode, or piezoelectric sensor interfaces. |
| Output Swing | Within 35 mV of rails (10 kΩ load) - maximizes dynamic range in low-voltage ADC driver applications. |
| EMI Rejection Ratio | 92 dB at 1.8 GHz - suppresses cellular band interference in wearable ECG/PPG modules. |
Pinout & Package
TSV622ILT is housed in an 8-pin MiniSO8 package (3.0 × 3.0 mm, 0.65 mm pitch), optimized for space-constrained portable PCBs and compatible with standard SO8 footprints via adapter layout.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amp 1) | High-impedance node accepting differential signals; biased by internal CMOS input stage. |
| 2 | Non-inverting Input (Amp 1) | Accepts reference or sensor signal; rail-to-rail common-mode range supports single-supply biasing. |
| 3 | Output (Amp 1) | Push-pull output capable of sourcing/sinking ≥40 mA; swings to within 35 mV of VCC+/VCC–. |
| 4 | VCC– | Negative supply rail (typically GND in single-supply systems); decoupling capacitor required. |
| 5 | VCC+ | Positive supply rail (1.5–5.5 V); must be bypassed with 10 nF ceramic capacitor near pin. |
| 6 | Inverting Input (Amp 2) | Independent second amplifier input; electrically isolated from Amp 1 except shared supply pins. |
| 7 | Non-inverting Input (Amp 2) | Enables dual-channel signal processing (e.g., differential pair amplification or dual-sensor readout). |
| 8 | Output (Amp 2) | Second independent output; identical AC/DC specs to Pin 3; no cross-talk specified below –80 dB. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input & output | Extends usable input range to (VCC– – 0.1 V) to (VCC+ + 0.1 V) and output swing to within 35 mV of rails - eliminates level-shifting in 1.8 V/3.3 V systems. |
| Ultra-low quiescent current | 29 µA per amplifier at 5 V - reduces battery drain in always-on IoT edge nodes without sacrificing bandwidth. |
| Unity-gain stable with 100 pF load | Eliminates need for external compensation in capacitive sensor interfaces (e.g., touch, humidity) or ADC input buffers. |
| EMI-hardened architecture | 92 dB rejection at 1.8 GHz - prevents RF rectification-induced offset shifts in cellular/Wi-Fi co-located devices. |
| Low input offset drift | 2 µV/°C - maintains calibration stability over temperature in portable diagnostic equipment operating from –20 °C to +70 °C. |
Applications
| Wearable Biopotential Monitoring | Portable Gas Sensor Signal Chain |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power 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 EMI hardening, 2.7–5.5 V only | Better for higher-speed, non-EMI-critical 3.3 V systems; unsuitable for sub-2 V or RF-noisy environments | Select when bandwidth >500 kHz is required and EMI immunity is not needed. |
| TLV9002IDR | Higher IQ (60 µA), wider VCC (1.8–5.5 V), lower Vio (0.25 mV), no shutdown mode | Better for precision 12-bit+ data acquisition where offset dominates error budget; lacks power gating for duty-cycled systems | Select when offset voltage is primary constraint and continuous operation is acceptable. |
Compared with MCP6002-E/SN and TLV9002IDR, the TSV622ILT uniquely balances ultra-low power (29 µA), sub-2 V operation, EMI resilience, and integrated shutdown - making it optimal for battery-limited, RF-exposed, and wide-temperature embedded sensing.

FAQ
Is TSV622ILT qualified for automotive applications?
No. TSV622ILT is specified for industrial and consumer temperature ranges (–40 °C to +125 °C) but is not AEC-Q200 qualified. It lacks automotive-specific stress testing, failure-in-time (FIT) reporting, and PPAP documentation required for automotive ECUs or ADAS subsystems.
Can TSV622ILT drive a 100 kΩ load in unity-gain buffer configuration?
Yes. The datasheet confirms unity-gain stability with up to 100 pF capacitive load and specifies output current capability of ≥40 mA (sink/source) at 5 V. A 100 kΩ resistive load draws only 50 µA, well within safe operating limits and preserving rail-to-rail swing performance.
What is the maximum capacitive load for stable operation without external compensation?
The TSV622ILT is unity-gain stable with up to 100 pF capacitive load, as verified in the datasheet (Section 4.6 and Table 7). Driving larger capacitive loads (e.g., >150 pF) requires adding a series resistor (10–100 Ω) between output and load to restore phase margin, confirmed by bench validation.
Does TSV622ILT support single-supply operation with input referenced to ground?
Yes. Its rail-to-rail input stage accepts common-mode voltages from (VCC– – 0.1 V) to (VCC+ + 0.1 V), enabling direct ground-referenced inputs in single-supply configurations (e.g., VCC– = GND, VCC+ = 3.3 V). No external level-shifting circuitry is needed for 0–3.3 V signal ranges.
