DESCRIPTION
The INA217 is a low-noise, low-distortion, monolithic instru-
mentation 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 band-
width.
Unique distortion cancellation circuitry reduces distortion to
extremely low levels, even in high gain. The INA217 provides
near-theoretical noise performance for 200Ω source imped-
ance. The INA217 features differential input, low noise, and
low distortion that provides superior performance in profes-
sional 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 pin outs 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.
