Product details
Overview
TSV622AILT from STMicroelectronics is a dual rail-to-rail input/output CMOS operational amplifier optimized for ultra-low-power, low-voltage operation. It delivers 420 kHz gain bandwidth at 29 µA supply current (5 V), supports 1.5–5.5 V supply range, features 800 µV max input offset voltage (A-grade), and operates across –40 °C to +125 °C - ideal for precision sensor signal conditioning in portable medical devices.
For engineers reviewing the TSV622AILT datasheet, TSV622AILT pinout, TSV622AILT application, or TSV622AILT equivalent, key selection criteria include its rail-to-rail I/O capability, 1 pA typical input bias current, shutdown-ready architecture (though not implemented in this dual variant), EMI-hardened performance (92 dB EMIRR at 1.8 GHz), and guaranteed unity-gain stability with 100 pF capacitive loads.
Technical Context
The TSV622AILT uses 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. Its output swings within 35 mV of both rails under 10 kΩ load, ensuring maximum dynamic range in single-supply systems.
It employs an internally trimmed current mirror architecture that tightly constrains supply current variation (±17% max), directly stabilizing GBP (min 350 kHz), slew rate (min 0.12 V/µs), and large-signal gain (min 85 dB) across process and temperature - critical for consistent active filter and transimpedance amplifier behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.5–5.5 V - enables direct integration into coin-cell (1.5 V) and Li-ion (3.3/5 V) powered systems without LDO overhead. |
| Quiescent Current | 29 µA typ @ 5 V - allows >1-year battery life in always-on wearable sensors drawing <10 µA average system current. |
| Gain Bandwidth | 420 kHz typ @ 5 V - supports anti-aliasing and sensor interface filters up to ~65 kHz while maintaining phase margin >40°. |
| Input Offset Voltage | 800 µV max (A-grade) - ensures ≤0.08% full-scale error in 1 V-range biomedical front-ends without trimming. |
| Input Bias Current | 1 pA typ - preserves high-impedance pH/electrochemical sensor node accuracy and prevents leakage-induced drift. |
| EMI Rejection Ratio | 92 dB @ 1.8 GHz - suppresses cellular band interference in portable diagnostic equipment near RF sources. |
| Capacitive Load Drive | Stable with ≤100 pF - permits direct connection to ADC input caps or long PCB traces without external isolation resistors. |
Pinout & Package
TSV622AILT is housed in an 8-pin MiniSO8 package (3.0 × 3.0 mm, 0.65 mm pitch), optimized for space-constrained portable designs and compatible with standard SO8 reflow profiles. The package meets ECOPACK® environmental compliance standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Amplifier 1 output | Delivers rail-to-rail swing (≤35 mV from rails) into ≥10 kΩ loads; high-Z in shutdown (not applicable to TSV622AILT). |
| 2 (−IN1) | Inverting input, Amp 1 | Accepts signals down to VCC– – 0.1 V; 1 pA bias current minimizes error in high-Z sensor interfaces. |
| 3 (+IN1) | Non-inverting input, Amp 1 | Supports common-mode range up to VCC+ + 0.1 V - enables direct sensing of battery voltage or rail monitoring. |
| 4 (VCC–) | Negative supply / ground | Reference for dual-supply operation or GND in single-supply systems; decoupling cap required per datasheet (10 nF). |
| 5 (+IN2) | Non-inverting input, Amp 2 | Independent channel with identical rail-to-rail input specs; enables differential pair or dual-path signal processing. |
| 6 (−IN2) | Inverting input, Amp 2 | Matches Amp 1's 1 pA bias and 800 µV offset - ensures matched DC performance in instrumentation amplifier configurations. |
| 7 (OUT2) | Amplifier 2 output | Functionally identical to OUT1; supports independent gain stages or buffered reference generation. |
| 8 (VCC+) | Positive supply | Accepts 1.5–5.5 V; internal regulation ensures stable GBP and SR across full voltage range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input & output | Extends usable input range to VCC– – 0.1 V / VCC+ + 0.1 V and output swing to within 35 mV of rails - maximizes SNR in low-voltage ADC interfaces. |
| Ultra-low input bias current | 1 pA typical - eliminates loading errors on high-impedance sources (e.g., glass pH electrodes, piezoelectric sensors) without guard rings. |
| EMI-hardened architecture | 92 dB rejection at 1.8 GHz - maintains signal integrity in Bluetooth/Wi-Fi coexistence environments without shielding or layout penalties. |
| Guaranteed unity-gain stability | Stable with 100 pF capacitive load - removes need for output series resistors in ADC driver or filter applications, simplifying BOM. |
| Tight parameter distribution | ±17% supply current spread - ensures predictable GBP (≥350 kHz) and slew rate (≥0.12 V/µs) across production lots for reliable filter design. |

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 |
|---|---|---|---|
| TSV622IST | Same silicon, SO8 package (4.9 × 6.0 mm vs. MiniSO8's 3.0 × 3.0 mm); 125 °C max Tj vs. 150 °C for AILT. | Larger footprint; less suitable for ultra-compact wearables but easier hand-soldering and thermal relief. | Select when board space allows SO8 and thermal margin >25 °C suffices. |
| MCP6002T-I/SN | Higher 100 µA ICC, lower 1 MHz GBP, no EMI hardening, 2 mV Vos max - broader parametric spread. | Acceptable for non-critical consumer sensors but lacks ECG-grade DC precision and RF immunity. | Choose only for cost-sensitive, non-medical, non-RF environments where 2 mV offset is tolerable. |
Compared with TSV622AILT, TSV622IST trades miniaturization for manufacturability and thermal headroom, while MCP6002T-I/SN sacrifices precision, EMI resilience, and power efficiency for broad-market availability - making TSV622AILT the sole choice for space-constrained, high-accuracy, RF-hostile portable medical designs.

FAQ
Is TSV622AILT pin-compatible with other TSV62x variants?
Yes - TSV622AILT (MiniSO8) shares identical pinout with TSV622IST (SO8) and TSV622IDT (TSSOP8). All dual versions use the same 1–8 pin mapping: OUT1, −IN1, +IN1, VCC–, +IN2, −IN2, OUT2, VCC+. This enables drop-in replacement across packages when board layout allows.
Does TSV622AILT support shutdown functionality?
No - the TSV622AILT is the base dual version without shutdown pins. Shutdown is only available on quad variants (TSV625/TSV625A) and duals with "3" suffix (TSV623/TSV623A), which add dedicated SHDN1/SHDN2 terminals. This simplifies design for always-on applications needing minimal external control logic.
What decoupling capacitance is required for stable operation?
A 10 nF ceramic capacitor must be placed as close as possible to both VCC+ and VCC– pins, per STMicroelectronics' layout guidance. This mitigates supply noise coupling and ensures phase margin remains >40° under all load conditions, especially critical at 420 kHz GBP.
Can TSV622AILT drive ADC inputs directly?
Yes - its rail-to-rail output (≤35 mV from rails), low 0.12 V/µs min slew rate, and unity-gain stability with 100 pF loads allow direct connection to SAR and sigma-delta ADC inputs. For 16-bit+ resolution, ensure Vos (≤800 µV) and THD+N (0.002%) meet your effective number of bits (ENOB) target.
