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.

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 200Ω source impedances. Many industrial applications also benefit from its low noise and wide bandwidth.

NOTES: (1) Gains other than 1 and 100 can be set by adding an external resistor, RG between pins 2 and 15. Gain accuracy is a function of RG. (2) FS = Full Scale. (3) Adjustable to zero. (4) VO = 0V, see Typical Curves for VCM vs VO. (5) VNOISE RTI = √V2N INPUT + (VN OUTPUT/Gain)2 + 4KTRG. See Typical Curves. (6) Time required for output to return from saturation to linear operation following the removal of an input overdrive voltage.

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.
