This document describes the TSH340 single supply voltage video buffer. Its features include a bandwidth of 320MHz, low harmonic distortion, low input and output rail, a slew rate of 780V/µs, voltage input noise of 7nV/√Hz, etc. It has an internal gain of 6dB, is specified for 150Ω and 100Ω loads, and is compatible with the PCB layout of a single op-amp. The product is tested on a 5V power supply.
The TSH340 is a high-speed operational amplifier designed as a single-supply video buffer. It features an internal gain of 6dB and a large bandwidth of 320MHz while consuming only 9.8mA of quiescent current. A key advantage is its input and output negative rail, which is very close to ground (tested at a maximum of 60mV from GND on a 150Ω load), making it ideal for driving video signals on standard 75Ω lines.
| Bandwidth (-3dB) | 320 MHz |
|---|---|
| Slew Rate | 780 V/µs |
| Input Noise Voltage | 7 nV/√Hz |
| Quiescent Current | 9.8 mA |
| DC Voltage Gain | 2 V/V (6dB) |
| Operating Temperature Range | -40°C to +85°C |
The device operates with only 9.8mA of quiescent current.
The device draws 9.8mA of quiescent current when there is no load and the input is at 100mV.
The -3dB bandwidth is 320MHz when the output voltage is 20mV peak and the load is 150Ω.
