Product details
Overview
TSH80IYLT from STMicroelectronics is a single, rail-to-rail output, wide-band 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, operates from 4.5–12 V supply, and drives 150 Ω loads with <0.1% THD at 4 MHz - deployed in automotive-grade video buffers and precision analog front-ends.
For engineers reviewing the TSH80IYLT datasheet, TSH80IYLT pinout, TSH80IYLT application, or TSH80IYLT equivalent, key selection criteria include its 100 MHz small-signal bandwidth under 150 Ω load, fast 2 µs wake-up from standby mode, rail-to-rail output swing capability, and automotive qualification (AEC-Q100 Grade 2) supporting robust operation from −40 °C to +85 °C.
Technical Context
The TSH80IYLT employs a high-speed current-feedback architecture optimized for video and high-speed data acquisition. Its internal compensation ensures stable operation with gain ≥ +2 and 150 Ω resistive + capacitive loads up to 30 pF, while maintaining >40° phase margin. The device supports both single-supply (4.5–12 V) and split-supply (±2.5 V to ±5 V) configurations.
Standby mode is controlled via a dedicated logic input (pin 5), reducing supply current to <10 µA while preserving high-impedance output state (ZOUT = 10 MΩ || 17 pF). Input common-mode range extends from VCC− to (VCC+ − 1.1 V), enabling direct interfacing with ADC reference voltages and DAC outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (−3 dB) | 100 MHz at AV = +1, RL = 150 Ω // 30 pF - enables full HD video (720p/1080i) signal amplification without group delay distortion. |
| Slew Rate | 100 V/µs - supports clean 2 VPP step response at 4.5 MHz with <1% overshoot into 150 Ω. |
| Output Current | ±55 mA - drives standard 150 Ω video termination and dual 75 Ω lines simultaneously. |
| THD+N | −61 dB (1 VPP, 4 MHz, RL = 150 Ω) - meets broadcast-grade video fidelity requirements per CCIR 330. |
| Supply Range | 4.5 V to 12 V single supply or ±2.5 V to ±5 V dual supply - compatible with 5 V and 10 V industrial and automotive rails. |
| Standby Wake-up Time | 2 µs - allows dynamic power gating in battery-sensitive or thermally constrained systems without signal interruption. |
| Input Offset Drift | 2 µV/°C - ensures <1 mV total offset shift over −40 °C to +85 °C, critical for DC-coupled sensor interfaces. |
Pinout & Package
SOT23-5 micropackage (2.9 mm × 1.6 mm × 1.1 mm), surface-mount, lead-free, RoHS-compliant, qualified per AEC-Q100 Grade 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 (IN−) | Inverting input | Differential input node; supports unity-gain inverter or transimpedance configurations with stable phase margin. |
| 3 (V−) | Negative supply rail | Accepts GND (single supply) or negative voltage (e.g., −2.5 V); supports asymmetrical supplies down to V− = −5 V. |
| 4 (OUT) | Amplified output | Rail-to-rail swing (within 48 mV of rails at 150 Ω), capable of sourcing/sinking 55 mA - directly terminates video lines. |
| 5 (STBY) | Standby control input | CMOS-compatible logic input: low = active mode (ICC ≈ 10 mA), high = standby (ICC < 10 µA); no external pull-up required. |
Key Features
| Feature | Design Value |

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 bandwidth (1.5 GHz), but requires ±5 V minimum supply and lacks standby mode; ICC = 14.5 mA vs. 10.5 mA typ. | Targeted at RF/IF signal chains, not video termination; no AEC-Q100 qualification. | Select when >500 MHz small-signal bandwidth is mandatory and automotive qualification is not required. |
| ADA4891-1ARJZ-R7 | Lower bandwidth (225 MHz), no standby function, lower output current (125 mA), but offers rail-to-rail input; ICC = 4.4 mA. | Optimized for portable instrumentation; not qualified for automotive temperature range or vibration. | Select for cost-sensitive, low-power, non-automotive applications requiring rail-to-rail input and moderate speed. |
Compared with LMH6629MA/NOPB and ADA4891-1ARJZ-R7, the TSH80IYLT uniquely balances 100 MHz bandwidth, 55 mA drive, standby power gating, and AEC-Q100 Grade 2 compliance - making it the only drop-in solution for automotive video buffer designs requiring thermal robustness and dynamic power control.

FAQ
What is the maximum capacitive load the TSH80IYLT can drive while maintaining stability?
The TSH80IYLT remains stable driving up to 30 pF in parallel with a 150 Ω load (e.g., coaxial cable + connector capacitance), as verified by >40° phase margin in Figure 3 and Figure 18 of the datasheet. For loads exceeding 30 pF, external series resistance (≥10 Ω) at the output is recommended to preserve transient response and prevent peaking.
Does the TSH80IYLT support single-supply operation with input signals near ground?
Yes - the input common-mode voltage range extends down to VCC− (GND in single-supply mode), allowing direct interface with ground-referenced sources such as DAC outputs or sensor bridges. However, the minimum input voltage is limited to VCC−; inputs below this level may cause phase reversal or increased offset.
How does the standby mode affect output state and signal integrity?
In standby mode, the output enters high-impedance state (ZOUT = 10 MΩ || 17 pF) with no DC path to either rail, preventing loading of downstream circuitry. There is no leakage current or bias shift; the output remains electrically isolated until wake-up completes in 2 µs, ensuring glitch-free reactivation in synchronous video systems.
Is the TSH80IYLT pin-compatible with other devices in the TSH8x family?
Yes - the TSH80IYLT (single channel, SOT23-5) shares identical pinout with the TSH81 (dual) in SO8 and TSH82 (quad) in SO14 packages for IN+, IN−, V−, OUT, and STBY functions. However, channel count and package differ; PCB layout must match the specific variant's footprint and thermal pad requirements.
