Product details
Overview
TSV7722IQ2T from STMicroelectronics is a dual, rail-to-rail output operational amplifier optimized for high-accuracy, high-bandwidth sensor signal conditioning in automotive and industrial systems. It delivers 22 MHz gain bandwidth, 50 µV typical input offset voltage, 2 pA typical input bias current, and operates from 1.8 V to 5.5 V single supply - enabling precision low-side current sensing and photodiode amplification.
For engineers reviewing the TSV7722IQ2T datasheet, TSV7722IQ2T pinout, TSV7722IQ2T application, or TSV7722IQ2T equivalent, key selection criteria include its rail-to-rail output swing, low-voltage operation down to 1.8 V, ultra-low input bias current for high-impedance sensors, and guaranteed performance over –40 °C to +125 °C for automotive-grade designs.
Technical Context
The TSV7722IQ2T implements a unity-gain-stable voltage-feedback architecture with 22 MHz GBW and 11 V/µs slew rate, supporting fast settling (270 ns to 0.1%) into 47 pF loads. Its input stage features low-voltage PNP differential pairs enabling common-mode range extending to VCC– – 0.1 V - critical for low-side shunt monitoring.
It achieves 99 dB CMRR and 108 dB PSRR at 25 °C, with input offset drift limited to ±4 µV/°C over –40 °C to +125 °C. The device draws only 1.7 mA per channel at 5 V, delivering high speed/power efficiency without requiring external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 22 MHz - supports closed-loop bandwidth up to ~18 MHz in unity-gain buffer configuration for high-speed sensor interfaces. |
| Input Offset Voltage | 50 µV typ., 200 µV max. - enables sub-100 µV system-level error in precision current sensing with 10 mΩ shunts. |
| Input Bias Current | 2 pA typ. - permits direct connection to photodiodes and high-Z strain gauges without signal degradation. |
| Supply Voltage Range | 1.8 V to 5.5 V - compatible with modern low-voltage microcontrollers and battery-powered automotive modules. |
| Common-Mode Input Range | VCC– – 0.1 V to VCC+ – 1.1 V - allows accurate amplification of signals referenced to ground (e.g., low-side current sense). |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADC inputs without level-shifting circuitry. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive applications per AEC-Q100 Grade 1. |
Pinout & Package
TSV7722IQ2T is housed in a MiniSO8 package (3.9 mm × 4.9 mm, 1.25 mm height), with exposed pad connected to VCC– for thermal and noise performance. Pinout matches industry-standard dual op-amp layout for drop-in compatibility with legacy SO8 footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Channel 1 output - rail-to-rail capable, drives ADC inputs or downstream analog stages directly. |
| 2 | IN1– | Inverting input for Channel 1 - used in transimpedance or differential configurations with matched feedback networks. |
| 3 | IN1+ | Non-inverting input for Channel 1 - accepts low-rail common-mode signals (e.g., shunt voltage) without clipping. |
| 4 | VCC– | Negative supply terminal - reference node for both channels; exposed pad must be soldered to PCB ground plane. |
| 5 | IN2+ | Non-inverting input for Channel 2 - independent input path enables dual-sensor conditioning on single die. |
| 6 | IN2– | Inverting input for Channel 2 - supports matched dual-channel current measurement with shared reference. |
| 7 | OUT2 | Channel 2 output - fully isolated from OUT1; channel separation >120 dB prevents crosstalk in multi-signal systems. |
| 8 | VCC+ | Positive supply terminal - accepts 1.8–5.5 V; internal regulation ensures stable biasing across voltage range. |
Key Features
| Feature | Design Value |
|---|---|
| Low input offset drift | ±4 µV/°C - minimizes temperature-induced error accumulation in long-duration automotive diagnostics. |
| EMI rejection | Measured EMIRR >70 dB from 400 MHz–2.4 GHz - reduces RF rectification artifacts in noisy engine control environments. |
| Stability with capacitive loads | Specified for 47 pF - eliminates need for external compensation in ADC driver applications. |
| Ultra-low noise density | 7 nV/√Hz at 10 kHz - preserves SNR in photodiode and piezoelectric sensor front-ends. |
| High CMRR at low rail | 99 dB at Vicm = 0 V - rejects ground bounce and power rail noise during low-side sensing. |
Applications
| Low-Side Current Measurement | Photodiode Amplification |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV792IDT | 50 MHz GBW, 3.3 mA/ch supply current, same MiniSO8 package | Better suited for higher-bandwidth closed-loop control loops (>30 MHz required) | Select when bandwidth >25 MHz is mandatory; trade-off is +94% quiescent current vs. TSV7722IQ2T. |
| TSB7192CDT | 22 MHz GBW, 36 V max. supply, 2.5 mA/ch, SO8 package | Supports industrial 24 V systems but lacks AEC-Q100 qualification | Choose for non-automotive 24 V sensor nodes where extended voltage range outweighs automotive qualification needs. |
Compared with TSV7722IQ2T, TSV792IDT trades higher power for greater bandwidth, while TSB7192CDT sacrifices automotive qualification for wider supply range - neither matches the TSV7722IQ2T's combination of low-voltage operation, AEC-Q100 Grade 1 rating, and sub-200 µV offset in MiniSO8.

FAQ
What is the maximum capacitive load the TSV7722IQ2T can drive without external compensation?
The TSV7722IQ2T is fully specified and stable driving up to 47 pF capacitive load in unity-gain configuration, as verified in the DS13614 datasheet. For loads exceeding 47 pF, stability may degrade - ringing and overshoot appear in step response. A series isolation resistor (10–22 Ω) between output and load restores stability while preserving DC accuracy, per Figure 35 and Section 5.6 of the datasheet.
Does the TSV7722IQ2T support true rail-to-rail input operation?
No - the TSV7722IQ2T features rail-to-rail *output* swing but has a limited input common-mode range: VCC– – 0.1 V to VCC+ – 1.1 V. Its input stage is optimized for low-rail operation (down to VCC– – 0.1 V), making it ideal for low-side current sensing, but it cannot accept signals within 1.1 V of VCC+. This is explicitly defined in Table 5 and Section 5.1 of DS13614.
How is the exposed thermal pad on the MiniSO8 package intended to be connected?
The exposed pad on the TSV7722IQ2T MiniSO8 package (pin 4 is VCC–; pad is internally tied to VCC–) must be soldered to a PCB copper pour connected to the system ground plane. This improves thermal dissipation (reducing θJA from 127 °C/W to ~70 °C/W in typical layouts) and lowers noise coupling. Leaving it floating degrades thermal performance and EMI immunity, per datasheet note in Section 1.2.
Is the TSV7722IQ2T qualified for automotive use per AEC-Q100?
Yes - the TSV7722IQ2T is AEC-Q100 Grade 1 qualified (–40 °C to +125 °C ambient), with full characterization across temperature and supply voltage per DS13614 Rev 7. It meets stress test requirements including HTOL, TC, UHAST, and ESD (4 kV HBM, 1.5 kV CDM). The "Automotive grade" designation in the datasheet features list confirms this qualification status.
