Product details
Overview
TSH82IYDT from STMicroelectronics is a wide-band, rail-to-rail output operational amplifier with standby function, designed for high-fidelity video signal conditioning and A/D converter driving in automotive-qualified systems. It delivers 100 MHz bandwidth, 100 V/µs slew rate, ±55 mA output current, operates from 4.5–12 V single or dual supply, and drives 150 Ω loads with 0.1% THD.
For engineers reviewing the TSH82IYDT datasheet, TSH82IYDT pinout, TSH82IYDT application, or TSH82IYDT equivalent, key selection criteria include its 100 MHz small-signal bandwidth at AV = +1, 100 V/µs slew rate under 150 Ω//30 pF load, standby mode switching time (Ton = 2 µs), differential gain/phase accuracy (0.5% / 0.5° at 4.5 MHz), and SO8 package compatibility with video layout constraints.
Technical Context
The TSH82IYDT implements a fully differential input stage with rail-to-rail output swing, optimized for unity-gain stable operation into 150 Ω loads. Its internal architecture supports both single-supply (4.5–12 V) and symmetrical dual-supply (±2.5 V to ±5 V) configurations, with common-mode input range extending to within 1.1 V of either rail.
It features an active standby mode controlled by a dedicated logic input, reducing supply current to <10 µA while maintaining high-impedance output (Zout ≈ 10 MΩ || 17 pF). Video performance is validated per CCIR330 line standards, with gain flatness ≤0.2 dB up to 6 MHz and channel separation ≥65 dB from 1–10 MHz.
Key Specifications

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 standby mode; SO8 package | Better for RF IF amplification; unsuitable for 150 Ω video load driving or power-gated systems | Select when bandwidth >500 MHz is required and load impedance ≥600 Ω |
| ADA4891-1ARJZ-R7 | Lower 225 MHz GBW; 110 mA output; no standby; SOT-23-5 only; not automotive qualified | Cost-optimized for consumer portable video; lacks AEC-Q100 validation and SO8 thermal performance | Select for non-automotive, space-constrained designs where 110 mA drive suffices and standby is unnecessary |
Compared with LMH6629MA/NOPB and ADA4891-1ARJZ-R7, the TSH82IYDT uniquely balances 100 MHz bandwidth, ±55 mA drive into 150 Ω, automotive qualification, and integrated standby-making it optimal for power-aware, safety-critical video signal chains where load matching and thermal reliability are mandatory.

FAQ
What is the maximum capacitive load the TSH82IYDT can drive while remaining stable?
The TSH82IYDT is unity-gain stable into 150 Ω resistive loads with up to 30 pF shunt capacitance, as verified in Figure 3 and Figure 18 of the datasheet. Stability margin drops below 40° phase margin when driving >47 pF directly; external series resistance (≥10 Ω) is recommended for loads exceeding 30 pF.
Does the TSH82IYDT support asymmetrical supply operation, such as +12 V and GND?
Yes - the device operates from 4.5–12 V single supply (VCC+ to GND) with VIC range from GND + 0.1 V to VCC+ − 1.1 V. Asymmetrical configurations like +12 V/GND are explicitly supported per Section 5 of the datasheet, and electrical characteristics are specified at 5 V and 10 V single-supply conditions.
How does the standby mode affect output impedance and DC offset?
In standby, output impedance rises to 10 MΩ || 17 pF (Table 5), effectively disconnecting the amplifier from the load. Input offset voltage and bias current become irrelevant as internal core is powered down; no DC path remains from input pins to output, preventing leakage-induced drift in downstream circuits.
Can the TSH82IYDT be used in inverting configuration with gain = −10?
Yes - Figure 4 and Table 4 confirm stable closed-loop operation at AV = −10 with 100 MHz bandwidth and 40° phase margin into 150 Ω. Layout requires matched feedback resistor pair (e.g., 1 kΩ/10 kΩ) and ground-plane isolation to maintain CMRR >72 dB across temperature.
