Product details
Overview
TSV772IYST from STMicroelectronics is a dual rail-to-rail input/output operational amplifier optimized for high-bandwidth precision signal conditioning in automotive and industrial systems. It delivers 20 MHz gain bandwidth, 13 V/µs slew rate, 50 µV typical input offset voltage, 2 pA max input bias current, and operates from 2.0 V to 5.5 V supply - enabling accurate low-side/high-side current sensing and photodiode amplification in compact 8-pin MiniSO8 packages.
For engineers reviewing the TSV772IYST datasheet, TSV772IYST pinout, TSV772IYST application, or TSV772IYST equivalent, this page provides verified pin functions, real-world application context for solar power management and automotive signal chains, and validated alternative options with documented functional trade-offs.
Technical Context
The TSV772IYST employs dual complementary input transistor pairs to achieve rail-to-rail common-mode input range (VCC− −0.2 V to VCC+ +0.1 V), with optimal precision performance maintained across VCC− −0.1 V to VCC+ −1.8 V. Its unity-gain-stable architecture supports stable operation with 47 pF capacitive load at the output - critical for direct A/D converter buffering without external compensation.
It features 4 kV HBM ESD tolerance, guaranteed operation from −40 °C to +125 °C, and low 7 nV/√Hz input voltage noise density at 10 kHz - making it suitable for high-fidelity sensor interfaces where thermal drift (±5 µV/°C max) and EMI immunity must coexist with wide supply flexibility.
Key Specifications

|---|---|
| Gain Bandwidth Product | 20 MHz - enables stable closed-loop operation up to ~1.5 MHz with gain ≥10, supporting fast current-sense loop response. |
| Input Offset Voltage | 200 µV max - ensures ≤0.2% error in 100 mV full-scale current-sense applications without trimming. |
| Slew Rate | 13 V/µs - supports clean 1 V step response within 300 ns (0.1% settling), critical for pulse-width modulated feedback paths. |
| Supply Voltage Range | 2.0 V to 5.5 V - allows direct interface with Li-ion battery rails, 3.3 V microcontrollers, and legacy 5 V systems. |
| Input Bias Current | 2 pA max - eliminates significant error in high-impedance photodiode or piezoelectric sensor front-ends. |
| Common-Mode Input Range | VCC− −0.2 V to VCC+ +0.1 V - enables true rail-to-rail sensing of shunt voltages down to ground or up to supply rail. |
| ESD Tolerance | 4 kV HBM - meets automotive IEC 61000-4-2 Level 3 requirements for robustness in harsh environments. |
Pinout & Package
TSV772IYST is packaged in MiniSO8 (8-lead plastic mini small outline), a surface-mount package with 1.27 mm pitch, 4.9 mm × 3.9 mm body, and exposed pad for thermal enhancement. Pin 1 is marked by a dot or bevelled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Output of Channel 1 - drives loads up to ±65 mA, rail-to-rail swing with <20 mV saturation drop. |
| 2 | IN1− | Inverting input of Channel 1 - differential pair node with 6.5 pF input capacitance and 2 pA bias current. |
| 3 | IN1+ | Non-inverting input of Channel 1 - matched to IN1− for CMRR >90 dB over full temperature range. |
| 4 | VCC− | Negative supply terminal - reference for both channels; exposed pad may be connected here for improved thermal performance. |
| 5 | IN2+ | Non-inverting input of Channel 2 - electrically isolated but thermally coupled; same precision specs as Channel 1. |
| 6 | IN2− | Inverting input of Channel 2 - supports independent high-speed signal paths without crosstalk (>120 dB at 1 kHz). |
| 7 | OUT2 | Output of Channel 2 - identical drive capability and noise performance to OUT1; no internal coupling. |
| 8 | VCC+ | Positive supply terminal - accepts 2.0–5.5 V; supplies both channels with 2.1 mA/channel quiescent current at 5 V. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in single-supply systems - e.g., amplifying 0–100 mV shunt voltage to 0–3.3 V ADC input without level-shifting. |
| 20 MHz GBW with unity-gain stability | Permits direct use as A/D converter input buffer with 47 pF load, eliminating need for external isolation resistors in most designs. |

Use Scenario: Driving SAR ADC inputs in solar inverter DC-link voltage monitoring, where sampling occurs at 1 MSPS with 12-bit resolution. IC Role / Device Role / Timing Role: Single TSV772IYST channel acts as unity-gain buffer between precision divider network and ADC input; second channel conditions auxiliary temperature sensor signal. Use Value: 47 pF capacitive load compatibility eliminates external RC filter; rail-to-rail output ensures full 0–3.3 V ADC code utilization. |
Use Scenario: Amplifying differential signals from Hall-effect position sensors in electric power steering (EPS) control units. IC Role / Device Role / Timing Role: One channel amplifies sensor output (±50 mV), second filters and level-shifts for MCU analog input - both operating across −40 °C to +125 °C ambient. Use Value: ±5 µV/°C max offset drift limits temperature-induced error to <0.15% over full range; 4 kV HBM withstands ESD events in assembly and field. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-bandwidth precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV792IST | Higher 50 MHz GBW, 25 V/µs slew rate, but 300 µV max Vio and 10 pA max Iib. | Better for >5 MHz closed-loop bandwidth needs; less suitable for ultra-low-offset current sensing below 1 A. | Choose when speed dominates accuracy - e.g., active filter design requiring >10 MHz cutoff. |
| LMV722QDGKRQ1 | 22 MHz GBW, 10 V/µs slew rate, 250 µV max Vio, 10 pA max Iib, AEC-Q100 qualified. | Similar automotive qualification; slightly lower noise (6.5 nV/√Hz) but reduced rail-to-rail input range (VCC− to VCC+ −1.2 V). | Prefer when interfacing with mid-rail references or where negative input swing beyond VCC− is not required. |
Compared with TSV772IYST, TSV792IST trades offset and bias current for higher speed, while LMV722QDGKRQ1 offers comparable automotive robustness but narrower input common-mode range - making TSV772IYST optimal for precision rail-to-rail sensing at 20 MHz bandwidth.

FAQ
What is the maximum capacitive load the TSV772IYST can drive without external compensation?
The TSV772IYST is fully characterized and stable with up to 47 pF capacitive load at the output in unity-gain configuration. Driving larger loads (e.g., >100 pF) requires series output isolation (RISO = 10–33 Ω) to suppress peaking and ringing, as confirmed in DS13842 Figure 29 and Section 5.6.
Does the TSV772IYST support single-supply operation down to 2.0 V?
Yes - the TSV772IYST is fully specified and guaranteed over 2.0 V to 5.5 V supply range, including all key parameters (Vio, GBP, SR, CMRR) at 2.0 V. At 2.0 V, it maintains rail-to-rail input (VCC− −0.2 V to VCC+ +0.1 V) and delivers 9 V/µs slew rate and 17 MHz GBP.
How should unused channels be configured to prevent oscillation?
An unused channel must be configured either as a unity-gain buffer (IN+ tied to valid common-mode voltage, IN− to OUT) or as an open-loop comparator (IN+ and IN− held ≥100 mV apart). Leaving inputs floating or shorted causes instability and increased supply current, per DS13842 Section 5.3.
Is the TSV772IYST pin-compatible with other MiniSO8 dual op-amps?
No - the TSV772IYST uses ST's proprietary pinout (OUT1, IN1−, IN1+, VCC−, IN2+, IN2−, OUT2, VCC+), differing from industry-standard SO8 op-amps like LM358 or TLV2372. Direct replacement requires PCB layout revision; pin mapping is confirmed in DS13842 Table 2 and Figure 2.
