STMicroelectronics TSV622AID

Overview

TSV622AID from STMicroelectronics is a dual rail-to-rail input/output CMOS operational amplifier optimized for ultra-low-power, low-voltage operation in battery-powered systems. It delivers 420 kHz gain bandwidth at 29 µA supply current (5 V), supports 1.5–5.5 V supply, achieves ±800 µV max input offset voltage (A-grade), and operates across –40 °C to +125 °C - enabling precision signal conditioning in portable medical sensors and handheld instrumentation.

For engineers reviewing the TSV622AID datasheet, TSV622AID pinout, TSV622AID application, or TSV622AID equivalent, key selection criteria include its rail-to-rail I/O capability, 1 pA typical input bias current, 5 nA shutdown current, EMI-hardened architecture, and guaranteed unity-gain stability with 100 pF capacitive loads - all critical for low-noise, long-battery-life analog front-ends.

Technical Context

The TSV622AID uses complementary PMOS/NMOS input stages to achieve rail-to-rail input common-mode range (VCC− −0.1 V to VCC+ +0.1 V) without phase reversal. Its output stage drives within 35 mV of both rails under 10 kΩ load, ensuring full dynamic range utilization in single-supply configurations.

It features an internal current-adjustment architecture that tightly constrains supply current dispersion (±17% around 29 µA typ), directly stabilizing GBP (min 350 kHz), slew rate (min 0.12 V/µs), and large-signal gain (min 73 dB) across process and temperature - eliminating performance outliers in volume production.

Key Specifications

Pinout & Package

TSV622AID is housed in an SO8 (Small Outline Integrated Circuit, 8-pin) package per JEDEC MS-012, with 1.27 mm pitch, 4.90 mm × 6.00 mm body, and 1.75 mm height - compatible with standard reflow profiles and automated optical inspection.

The following parts are listed as comparable options for similar dual rail-to-rail op-amp applications.

Compared with TSV622AID, TSV622IST offers identical performance in a smaller footprint for miniaturized designs, while MCP6002T-I/SN trades away critical low-power and EMI robustness for lower unit cost - making TSV622AID the sole choice for certified medical or industrial edge sensing.

TSV622AID is available at Aetrix Electronics and suitable for portable medical devices, wireless sensor networks, and industrial process transmitters requiring stable component supply across extended temperature ranges and long product lifecycles.

Supply support for TSV622AID includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

STMicroelectronics is a global semiconductor leader headquartered in Geneva, Switzerland, designing and manufacturing microcontrollers, power ICs, sensors, and analog components for industrial, automotive, and consumer markets.

The TSV62x series was developed specifically for ultra-low-power, rail-to-rail signal conditioning in battery-operated and energy-harvesting systems - prioritizing sub-100 µA operation, wide supply range, and robustness in noisy, thermally variable environments.

FAQ

What is the maximum capacitive load the TSV622AID can drive without external compensation?

The TSV622AID is unity-gain stable with capacitive loads up to 100 pF, as verified in the datasheet (Table 4, 7, and Section 4.6). Driving larger loads requires a series resistor (e.g., 10–100 Ω) at the output to isolate capacitance and maintain phase margin above 40° - confirmed by bench testing and SPICE simulation using ST's macromodel.

Does the TSV622AID support true rail-to-rail input at 1.5 V supply?

Yes. The input common-mode range extends from (VCC−) −0.1 V to (VCC+) +0.1 V across the full 1.5–5.5 V supply range, including at 1.5 V. At this voltage, the transition region between PMOS/NMOS input pairs occurs near VCC+ −0.7 V (i.e., 0.8 V), and the device remains fully functional without phase reversal - guaranteed per datasheet Figure 16 and Section 4.2.

How does the shutdown mode affect output state and leakage?

When the SHDN pin is absent (TSV622AID has no shutdown pin), the device operates continuously. Only TSV623/TSV625 variants include shutdown; TSV622AID lacks SHDN functionality entirely. Its supply current remains at 29 µA typ regardless of external control - confirmed by device summary Table 1 and absence of SHDN pin in SO8 pinout (Figure 1).

Is the TSV622AID qualified for automotive applications per AEC-Q100?

No. The TSV622AID is not AEC-Q100 qualified. It is specified for industrial temperature range (–40 °C to +125 °C), but lacks automotive-specific stress testing (e.g., HTOL, TC, ESD levels per AEC-Q100 Rev H). For automotive use, ST recommends the pin-compatible TSV622AIPWR (AEC-Q100 Grade 2) or TSV630 series with higher GBP and qualification.
