The INA217 device is a low-noise, low-distortion,

device is ideal for low-level audio signals such as
• High CMR: > 100 dB balanced low-impedance microphones. Many
• Gain Set With External Resistor industrial, instrumentation, and medical applications
• DIP-8 and SOL-16 Widebody Packages also benefit from its low noise and wide bandwidth.
Unique distortion cancellation circuitry reduces 2 Applications distortion to extremely low levels, even in high gain.
• Professional Microphone Preamps The INA217 device provides near-theoretical noise
performance for 200-Ω source impedance. The • Moving-coil Transducer Amplifiers INA217 device features differential input, low noise,
• Differential Receivers and low distortion that provides superior performance
• Bridge Transducer Amplifiers in professional microphone amplifier applications.
The INA217device 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 device 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
device in SO-14 narrow. The INA217 device is
specified over the temperature range of –40°C to
