Product details
Overview
TSH82IDT from STMicroelectronics is a wide-band, rail-to-rail operational amplifier with standby function, designed for high-fidelity video signal conditioning and A/D converter driving. It delivers 100 MHz bandwidth, 100 V/µs slew rate, ±55 mA output current, and operates from 4.5–12 V single or dual supply. It drives 150 Ω loads with <0.1% THD in video applications.
For engineers reviewing the TSH82IDT datasheet, TSH82IDT pinout, TSH82IDT application, or TSH82IDT equivalent, key selection criteria include its 100 MHz bandwidth at AV = +1, rail-to-rail output swing under 150 Ω load, fast 2 µs wake-up from standby, low 11 nV/√Hz input noise, and automotive qualification per AEC-Q100.
Technical Context
The TSH82IDT employs a high-speed voltage-feedback architecture optimized for unity-gain stable operation into reactive 150 Ω video loads. Its internal compensation ensures ≥40° phase margin with 150 Ω // 30 pF loads across ±2.5 V and ±5 V supplies.
It integrates a digital standby control input (pin 5) that reduces supply current to <10 µA while maintaining high-impedance output (10 MΩ || 17 pF). The amplifier supports asymmetrical supply operation and features robust CMRR (min 72 dB) and PSRR (min 75 dB) over temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6629MA/NOPB | Higher 1.5 GHz GBW but lower output current (±35 mA); no integrated standby function | Preferred for RF IF amplification, not optimized for 150 Ω video load drive | Select when >500 MHz small-signal bandwidth is required and standby is managed externally |
| ADA4891-2ARZ | Lower 225 MHz GBW; 110 mA output; no standby; wider supply range (2.7–12 V) | Better suited for general-purpose high-speed buffering where automotive qualification is not mandatory | Choose for cost-sensitive industrial cameras lacking AEC-Q100 requirement and needing higher output current |
Compared with LMH6629MA/NOPB and ADA4891-2ARZ, the TSH82IDT uniquely combines automotive qualification, integrated standby control, and guaranteed 150 Ω video load drive - making it the only drop-in solution for AEC-Q100-compliant video signal chains requiring low-power idle states.

FAQ
What is the minimum supply voltage for reliable operation of the TSH82IDT?
The TSH82IDT is specified to operate down to 4.5 V on the positive rail (VCC+) with VCC− at ground in single-supply mode, or ±2.25 V in dual-supply configuration. Below 4.5 V, output swing, bandwidth, and slew rate degrade - confirmed by electrical characteristics tables at VCC+ = +5 V and ±2.5 V conditions.
Does the TSH82IDT require external compensation for stability with 150 Ω loads?
No external compensation is required. The TSH82IDT is unity-gain stable into 150 Ω resistive loads and remains stable with up to 30 pF capacitive loading, as verified by phase margin ≥40° measurements in Figures 2, 4, 5, 17, 19, and 20 of the datasheet under both ±2.5 V and ±5 V supply conditions.
How does the standby function affect output impedance and signal integrity?
In standby mode, the output enters high-impedance state with ZOUT = 10 MΩ || 17 pF (typical), as specified in Table 5. This prevents loading of downstream circuitry and eliminates DC path leakage, enabling clean signal isolation during power gating - critical in multi-channel video switchers and portable devices.
Is the TSH82IDT pin-compatible with other devices in the TSH8x family?
Yes - the TSH82IDT (dual op-amp) shares identical SO8 pinout with TSH80 (single) and TSH84 (quad) variants. Pin 1 (IN+), pin 2 (IN−), pin 3 (VCC−), pin 4 (OUT), pin 5 (STBY), pin 6 (VCC+), and pins 7–8 (NC) are functionally mapped across all three, enabling footprint reuse in scalable designs.
