INA103数据手册TI中文资料规格书

描述 Description

The INA103 is a very low noise, low distortion monolithic instrumentation amplifier. Its current-feedback circuitry achieves very wide bandwidth and excellent dynamic response. It is ideal for low-level audio signals such as balanced low-impedance microphones. The INA103 provides near-theoretical limit noise performance for 200(ohm) source impedances. Many industrial applications also benefit from its low noise and wide bandwidth.
Unique distortion cancellation circuitry reduces distortion to extremely low levels, even in high gain. Its balanced input, low noise and low distortion provide superior performance compared to transformer-coupled microphone amplifiers used in professional audio equipment.
The INA103’s wide supply voltage (±9 to ±25V) and high output current drive allow its use in high-level audio stages as well. A copper lead frame in the plastic DIP assures excellent thermal performance.
The INA103 is available in 16-pin plastic DIP, 16-pin ceramic DIP and SOL-16 surface-mount packages. Commercial and industrial temperature range models are available.
