The INA103KU is a very low noise low distortion monolithic Instrumentation Amplifier for use with differential receivers. 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 200W 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 amplifier 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 INA114APG4 is a Precision Instrumentation Amplifier offers excellent accuracy. Its versatile 3 op-amp design and small size make it ideal for a wide range of applications. A single external resistor sets any gain from 1 to 10000. Internal input protection can withstand up to ±40V without damage. The INA114 is laser trimmed for very low offset voltage (50µV), drift (0.25µV/°C) and high common-mode rejection (115dB at G=1000). It operates with power supplies as low as ±2.25V, allowing use in battery operated and single 5V supply systems. Quiescent current is 3mA maximum.
