DESCRIPTION

The INA217 is a low-noise, low-distortion, monolithic instrumentation
amplifier. Current-feedback circuitry allows the
INA217 to achieve wide bandwidth and excellent dynamic
response over a wide range of gain. The INA217 is ideal for
low-level audio signals such as balanced low-impedance
microphones. Many industrial, instrumentation, and medical
applications also benefit from its low noise and wide bandwidth.
Unique distortion cancellation circuitry reduces distortion to
extremely low levels, even in high gain. The INA217 provides
near-theoretical noise performance for 200Ω source impedance.
The INA217 features differential input, low noise, and
low distortion that provides superior performance in professional
microphone amplifier applications.
The INA217 features wide supply voltage, excellent output
voltage swing, and high output current drive, making it an
optimal candidate for use in high-level audio stages.
The INA217 is available in the same DIP-8 and SOL-16 wide
body packages and pinouts as the SSM2017. For a smaller
package, see the INA163 in SO-14 narrow. The INA217 is
specified over the temperature range of –40°C to +85°C.
