Product details
Overview
TSV772IDT 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, and operates from 2.0 V to 5.5 V single supply - enabling accurate low-side current sensing and photodiode amplification in battery-constrained 3.3 V or 5 V designs.
For engineers reviewing the TSV772IDT datasheet, TSV772IDT pinout, TSV772IDT application, or TSV772IDT equivalent, this device is selected for high-frequency analog front-ends requiring low noise (7 nV/√Hz at 10 kHz), 4 kV HBM ESD tolerance, extended temperature operation (–40 °C to +125 °C), and stable unity-gain performance with 47 pF capacitive load.
Technical Context
The TSV772IDT 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 precision optimized over the low-pair region (VCC− −0.1 V to VCC+ −1.8 V). Its 20 MHz GBP and 13 V/µs slew rate support fast settling (300 ns to 0.1%) in closed-loop configurations.
It features internal compensation for unity-gain stability, 95 dB minimum open-loop gain at 125 °C, and 90 dB minimum CMRR across full temperature range - ensuring robust performance in noisy automotive environments where supply rejection (90–110 dB SVR) and EMI immunity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 20 MHz - enables stable closed-loop operation up to 10× gain at 2 MHz or unity gain at 20 MHz for sensor buffering and active filtering. |

Pinout & Package
TSV772IDT is supplied in MiniSO8 package (3.0 mm × 4.9 mm, 1.27 mm pitch), with exposed pad connected to VCC− for thermal enhancement and noise reduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplified output of Channel 1; rail-to-rail swing supports full dynamic range utilization into ADC inputs. |
| 2 | IN1− | Inverting input of Channel 1; matched to IN1+ for <200 µV offset and high CMRR in differential configurations. |
| 3 | IN1+ | Non-inverting input of Channel 1; accepts signals down to VCC− −0.2 V, enabling true single-supply high-side sensing. |
| 4 | VCC− | Negative supply terminal; also serves as thermal and EMI reference node when exposed pad is tied here. |
| 5 | IN2+ | Non-inverting input of Channel 2; independent biasing allows dual-path signal conditioning without crosstalk (120 dB). |
| 6 | IN2− | Inverting input of Channel 2; identical electrical specs to Channel 1 for matched dual-channel designs. |
| 7 | OUT2 | Amplified output of Channel 2; fully isolated from OUT1 - no shared output stage limiting drive capability. |
| 8 | VCC+ | Positive supply terminal; supplies both channels; 5.5 V max rating supports transient overvoltage margin in automotive 12 V systems. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full-scale signal acquisition from 0 V to VCC in single-supply systems - eliminates level-shifting in solar MPPT or battery monitoring. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-bandwidth, low-offset op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV792IDT | 50 MHz GBP, 22 V/µs slew rate, 150 µV max Vio, but higher ICC (3.5 mA/ch) and narrower supply range (2.7–5.5 V). | Better for >5 MHz closed-loop filters or fast pulse amplification; less suitable for ultra-low-power solar-powered systems. | Select when bandwidth >30 MHz is required and quiescent current budget allows ≥1.5× increase. |
| OPA2333AIDR | Zero-drift architecture, 12 µV max Vio, 350 kHz GBP, 0.16 V/µs slew rate, 17 µA ICC - optimized for DC precision, not speed. | Ideal for weigh scales or thermopile amplifiers; cannot replace TSV772IDT in photodiode or current-sense applications demanding >1 MHz BW. | Choose only if sub-20 µV offset dominates design priority and bandwidth needs are <500 kHz. |
Compared with TSV772IDT, TSV792IDT trades lower power and wider supply for higher speed and cost, while OPA2333AIDR sacrifices bandwidth and slew rate to achieve nanovolt-level DC stability - making TSV772IDT the optimal balance for 1–10 MHz signal chains needing both speed and precision.

FAQ
Is TSV772IDT pin-compatible with other dual op amps in MiniSO8?
No - TSV772IDT uses a non-standard pinout: OUT1/IN1−/IN1+/VCC−/IN2+/IN2−/OUT2/VCC+. It differs from industry-standard dual op amps like LMV358 or MCP6022, which place VCC+ on Pin 8 and VCC− on Pin 4. Direct replacement requires PCB redesign or adapter.
Can TSV772IDT drive a 100 pF capacitive load stably in unity gain?
No - the datasheet specifies stable operation only up to 47 pF without external compensation. Driving 100 pF requires adding a 10–33 Ω isolation resistor (RISO) in series with each output to suppress peaking and ringing, verified by phase margin >50° in simulation.
What is the maximum output current per channel at 125 °C?
At –40 °C to +125 °C, the guaranteed minimum output sink/source current is 30 mA per channel (tested at VCC = 5 V). This supports driving 160 Ω loads to rail while maintaining linearity - sufficient for driving ADC reference buffers or LED bias circuits.
Does TSV772IDT require external compensation for gain-of-10 configuration?
No - the device is internally compensated for unity-gain stability, and gain-of-10 operation is inherently more stable. No external components are needed; however, layout best practices (short traces, ground plane, local 100 nF decoupling at Pins 4 and 8) remain essential for EMI immunity and thermal performance.
