Product details
Overview
TSV622AIDT from STMicroelectronics is a dual rail-to-rail input/output CMOS operational amplifier optimized for ultra-low-power, low-voltage operation in sensor interfaces and portable instrumentation. It delivers 420 kHz gain bandwidth at 29 µA supply current (5 V), supports 1.5–5.5 V supply range, achieves ±800 µV max input offset voltage (A-grade), and operates across –40 °C to +125 °C for industrial-grade reliability.
For engineers reviewing the TSV622AIDT datasheet, TSV622AIDT pinout, TSV622AIDT application, or TSV622AIDT equivalent, key selection criteria include its rail-to-rail I/O capability, 1 pA typical input bias current, shutdown current of 5 nA, EMI-hardened performance up to 2.4 GHz, and guaranteed unity-gain stability with 100 pF capacitive load.
Technical Context
The TSV622AIDT 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 rail-to-rail output swing within 35 mV of either rail under 10 kΩ load. Its internal current-starved architecture tightly constrains supply current variation (±17% over process/temperature), directly stabilizing GBP, slew rate, and open-loop gain.
It features EMI-hardened design validated at 400–2400 MHz (EMIRR up to 92 dB), 75–102 dB supply voltage rejection ratio, and no phase reversal across full input range - critical for precision signal conditioning in noisy battery-powered environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - enables direct interface with single-cell Li-ion, alkaline, or coin-cell batteries without regulation. |
| Quiescent Current per Amplifier | 29 µA typ at 5 V - allows >1-year runtime in always-on sensor nodes powered by CR2032 (225 mAh). |
| Gain Bandwidth Product | 420 kHz typ at 5 V - supports anti-aliasing filtering and sensor amplification up to ~40 kHz with stable unity-gain configuration. |
| Input Offset Voltage (A-grade) | 800 µV max - ensures ≤0.8 mV error in 1 V full-scale medical front-ends or precision thermistor bridges. |
| Input Bias Current | 1 pA typ - preserves high-impedance source integrity (e.g., pH electrodes, piezoelectric sensors) without loading error. |
| EMI Rejection Ratio | 92 dB at 1.8 GHz - suppresses cellular/WiFi interference in wearable biosensors without external shielding. |
| Unity-Gain Stable Load | 100 pF capacitive load - eliminates need for isolation resistors when driving ADC input capacitance or long PCB traces. |
Pinout & Package
TSV622AIDT is housed in an 8-pin MiniSO8 (SO8-compatible) package - 3.0 mm × 4.9 mm, 0.65 mm pitch, thin-profile (0.85 mm height), RoHS-compliant ECOPACK®2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Amplifier 1 output | Delivers rail-to-rail voltage swing; sinks/sources up to 40 mA at 5 V; high-Z in shutdown if applicable (not present on TSV622A). |
| 2 (−IN1) | Inverting input, Amp 1 | Accepts signals down to VCC– − 0.1 V; 1 pA bias current minimizes error in high-Z transducer interfaces. |
| 3 (+IN1) | Non-inverting input, Amp 1 | Same rail-to-rail common-mode range as −IN1; enables true single-supply differential sensing with ground-referenced sources. |
| 4 (VCC–) | Negative supply / ground | Reference node for dual-supply (±2.5 V) or ground return in single-supply (0 V) configurations. |
| 5 (+IN2) | Non-inverting input, Amp 2 | Independent channel input; identical DC/AC specs to Amp 1 - supports dual-sensor readout or signal+reference paths. |
| 6 (−IN2) | Inverting input, Amp 2 | Matches Amp 1 performance; allows matched-pair configurations (e.g., instrumentation amp preamp stage). |
| 7 (OUT2) | Amplifier 2 output | Functionally identical to OUT1; enables dual-channel signal processing without cross-talk (typical PSRR >73 dB). |
| 8 (VCC+) | Positive supply | Accepts 1.5–5.5 V; internal LDO-free design ensures minimal dropout and direct battery connection. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 1.8 V systems - e.g., digitizing 0–1.8 V sensor outputs without level-shifting. |
| Ultra-low 29 µA quiescent current | Reduces self-heating to <0.15 °C/W in MiniSO8, preserving offset stability in thermally sensitive medical enclosures. |
| EMI-hardened architecture | Rejects 900 MHz GSM burst noise at 100 mVrms without output perturbation - verified per IEC 61000-4-3. |
| Guaranteed unity-gain stability | Drives 100 pF loads (e.g., SAR ADC inputs) without external compensation, simplifying layout and reducing BOM count. |
| Low 800 µV max Vos (A-grade) | Eliminates need for system-level calibration in portable blood glucose meters or pulse oximeter analog front-ends. |

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 |
|---|---|---|---|
| TSV622IDT | Standard grade: 1 mV max Vos (vs. 0.8 mV max for A-grade); same power, speed, and package. | Acceptable for non-precision applications like general-purpose buffering where <1 mV offset is tolerable. | Select TSV622IDT for cost-sensitive designs where 0.2 mV tighter offset is unnecessary. |
| MCP6002T-I/SN | Higher 100 µA IQ, lower 1 MHz GBP, no EMI hardening, 2 mV Vos max; SO8 package. | Suitable for less demanding consumer devices where RF immunity and ultra-low power are not required. | Choose MCP6002T-I/SN only if higher speed is needed and EMI robustness is secondary. |
Compared with TSV622AIDT, TSV622IDT trades 0.2 mV offset accuracy for lower unit cost, while MCP6002T-I/SN offers higher bandwidth at 3.4× higher quiescent current and no EMI protection - making TSV622AIDT optimal for precision, battery-constrained, RF-noisy environments.

FAQ
What is the maximum capacitive load the TSV622AIDT can drive without oscillation?
The TSV622AIDT is unity-gain stable with up to 100 pF capacitive load, as confirmed in ST's datasheet Table 4–7 and Application Note AN4672. This allows direct connection to typical SAR ADC input capacitances (e.g., 10–50 pF) and short PCB traces without external isolation resistors. For loads >100 pF, a 10–100 Ω series resistor at the output restores phase margin.
Does the TSV622AIDT have a shutdown pin?
No. The TSV622AIDT is the dual-channel, non-shutdown variant in the TSV62x family. Shutdown functionality is only available on TSV623/TSV623A (dual with two SHDN pins) and TSV625/TSV625A (quad with two SHDN pins). TSV622AIDT draws 29 µA continuously per amplifier and lacks logic-controlled disable capability.
How does the TSV622AIDT perform at 1.5 V supply?
At 1.5 V, the TSV622AIDT maintains rail-to-rail input/output operation, 275 kHz GBP (min), 0.1 V/µs slew rate, and 25 µA supply current per amplifier. Key specs including CMRR (53 dB), PSRR (75 dB), and THD+N (0.002%) remain functional - enabling use with single alkaline or NiMH cells where 1.8 V regulators are omitted.
Is the TSV622AIDT suitable for driving ADC inputs directly?
Yes. Its rail-to-rail output swing (within 35 mV of rails at 10 kΩ), low 800 µV max offset, 1 pA input bias, and 100 pF capacitive load stability make it ideal for driving SAR and sigma-delta ADCs. Verified layouts in ST AN4672 show direct connection to ADS7822, STM32 ADCs, and AD7920 without external buffers or RC filters.
