TSH70,71,72,73,74,75
Rail-to-Rail, Wide-Band, Low-Power Operational Amplifiers
■ 3V, 5V, ±5V specifications
■ 3dB bandwidth: 90MHz
■ Gain bandwidth product: 70MHz
■ Slew rate: 100V/ms
■ Input single supply voltage
■ Output rail-to-rail
■ Specified for 150Ω loads
■ Low distortion, THD: 0.1%
■ SOT23-5, TSSOP and SO packages
Description
The TSH7x series offers single, dual, triple and quad operational amplifiers featuring high video performances with large bandwidth, low distortion and excellent supply voltage rejection.
Running with a single supply voltage from 3V to 12V, these amplifiers feature a large output voltage swing and high output current capable of driving standard 150Ω loads. A low operating voltage makes TSH7x amplifiers ideal for use in portable equipment.
The TSH71, TSH73 and TSH75 also feature standby inputs, each of which allows the op-amp to be put into a standby mode with low power consumption and high output impedance. This function allows power saving or signal switching/multiplexing for high-speed applications and video applications.
To economize both board space and weight, the TSH7x series is proposed in SOT23-5, TSSOP and SO packages.
Applications
■ Video buffers
■ ADC driver
