Product details
Overview
TSV772IST 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 TSV772IST datasheet, TSV772IST pinout, TSV772IST application, or TSV772IST equivalent, this device is selected for demanding analog front-ends requiring stable DC accuracy, wide common-mode range (VCC− −0.2 V to VCC+ +0.1 V), low noise (7 nV/√Hz at 10 kHz), and AEC-Q100 qualified performance up to +125 °C.
Technical Context
The TSV772IST integrates two independent unity-gain-stable amplifiers with complementary differential input pairs - one optimized for low common-mode voltages (VCC− −0.1 V to VCC+ −1.8 V) and another extending operation up to VCC+ +0.1 V. Its rail-to-rail output stage supports full-swing drive into 10 kΩ loads while maintaining 45 mA sink/source capability per channel.
Designed for robustness in noisy environments, it features 4 kV HBM ESD tolerance, low EMIRR sensitivity (measured 400 MHz–2.4 GHz), and guaranteed stability with 47 pF capacitive load - eliminating need for external compensation in standard A/D buffer configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 20 MHz - enables closed-loop operation up to ~1.5 MHz at gain = 10 without phase margin degradation. |
| Input Offset Voltage | 200 µV max (−40 °C to +125 °C) - ensures ≤0.2% error in 100 mV full-scale current sense applications. |
| Slew Rate | 13 V/µs - supports clean 1 Vpp step response settling to 0.1% in 300 ns at AV = −1. |
| Supply Voltage Range | 2.0 V to 5.5 V - compatible with Li-ion, 3.3 V logic, and automotive 5 V domains without level shifting. |
| Input Bias Current | 2 pA max (25 °C) - preserves signal integrity in high-impedance photodiode and sensor interfaces. |
| Common-Mode Input Range | VCC− −0.2 V to VCC+ +0.1 V - allows direct connection to shunt resistors referenced to ground or supply rails. |
| ESD Tolerance | 4 kV HBM - meets IEC 61000-4-2 Level 3 requirements for board-level transient immunity. |
Pinout & Package
TSV772IST is supplied in MiniSO8 package (3.0 mm × 4.9 mm, 1.27 mm pitch), thermally enhanced with exposed pad connected to VCC− for improved power dissipation (RthJA = 127 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplified output of Channel 1; rail-to-rail swing supports direct interface to SAR ADC reference buffers. |
| 2 | IN1− | Inverting input of Channel 1; matched to IN1+ for <200 µV offset and >90 dB CMRR over temperature. |
| 3 | IN1+ | Non-inverting input of Channel 1; accepts signals down to VCC− −0.2 V for true single-supply low-side sensing. |
| 4 | VCC− | Negative supply terminal; internal ESD protection tied to exposed thermal pad (recommended connection). |
| 5 | IN2+ | Non-inverting input of Channel 2; electrically isolated from Channel 1 to prevent crosstalk (<120 dB @ 1 kHz). |
| 6 | IN2− | Inverting input of Channel 2; supports differential configurations with matched input capacitance (6.5 pF diff, 2.5 pF cm). |
| 7 | OUT2 | Amplified output of Channel 2; independently buffered to avoid loading effects on OUT1 in dual-path designs. |
| 8 | VCC+ | Positive supply terminal; supplies both channels; supports 2.0–5.5 V operation with <2.1 mA/ch quiescent current. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 2.0 V systems - e.g., 0–2.0 V output swing with 10 kΩ load and ±100 mV headroom. |
| 20 MHz GBW with unity-gain stability | Eliminates need for external compensation in gain ≥1 configurations - simplifies layout for current-sense filters. |
| 7 nV/√Hz input voltage noise (10 kHz) | Reduces integrated noise floor in 100 kHz bandwidth photodiode amps to <1.5 µVRMS, preserving SNR >85 dB. |
| Automotive-grade qualification | AEC-Q100 Grade 1 (−40 °C to +125 °C) with production test coverage - suitable for engine control and ADAS sensor interfaces. |
| 47 pF capacitive load drive | Guaranteed stable operation into typical ADC input capacitance without series isolation resistor - reduces BOM count. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV792IST | 50 MHz GBW, 22 V/µs SR, but 350 µV max Vio and no AEC-Q100 grade. | Better for wideband active filters; unsuitable for automotive temperature-critical current sensing. | Select when bandwidth >30 MHz required and offset drift <±5 µV/°C is not mandatory. |
| LMV722QMMX/NOPB | 10 MHz GBW, 5.5 V/µs SR, 400 µV max Vio, AEC-Q100 qualified but only to +105 °C. | Limited to lower-frequency sensor buffering; insufficient SR for 100 kHz photodiode pulse shaping. | Choose only for cost-sensitive non-automotive 3.3 V systems where 20 MHz is unnecessary. |
Compared with TSV772IST, TSV792IST trades offset accuracy and automotive qualification for higher speed, while LMV722QMMX sacrifices bandwidth and thermal range to meet lower cost targets - making TSV772IST the optimal balance of precision, speed, and ruggedness for automotive and industrial 2–5.5 V signal chains.

FAQ
What is the maximum capacitive load the TSV772IST can drive without external compensation?
The TSV772IST is fully characterized and guaranteed stable with 47 pF capacitive load in unity-gain configuration, matching typical SAR ADC input capacitance. For loads >47 pF, a 10–33 Ω isolation resistor (RISO) in series with the output is recommended to suppress peaking and ringing - confirmed by Figure 29 and Section 5.6 of DS13842 Rev 7.
Does the TSV772IST support true rail-to-rail input at 2.0 V supply?
Yes - the input common-mode range extends from VCC− −0.2 V to VCC+ +0.1 V. At 2.0 V supply (VCC− = 0 V), this means inputs operate from −0.2 V to +2.1 V, enabling direct interface to grounded shunts and sensors without level-shifting circuitry - verified in Table 6 and Section 5.1 of the datasheet.
How is unused channel termination handled to prevent oscillation?
An unused channel must be configured either as a unity-gain buffer (IN+ tied to any valid Vicm voltage, IN− to OUT) or as an open-loop comparator (IN+ and IN− held ≥100 mV apart within Vicm limits). Floating inputs or shorted configurations risk instability and increased supply current - detailed in Section 5.3 of DS13842 Rev 7.
Is the TSV772IST pin-compatible with other ST dual op amps in MiniSO8?
No - TSV772IST uses a unique pinout (OUT1, IN1−, IN1+, VCC−, IN2+, IN2−, OUT2, VCC+) differing from legacy ST dual op amps like TS912 or TSV632. Direct replacement requires PCB redesign; pin compatibility is only guaranteed within the TSV77x family (TSV7721/7722 share same pinout).
