Nisshinbo NL9620 Precision Instrumentation Amplifiers
Nisshinbo NL9620 Precision Instrumentation Amplifiers are high-precision, low-power instrumentation amplifiers designed for applications requiring accurate signal amplification with minimal noise and drift. Featuring a low input offset voltage of 125µV (maximum at +25°C) and a low input bias current of 2nA (maximum), the NL9620 ensures excellent DC accuracy, making it ideal for sensor signal conditioning, medical instrumentation, and industrial measurement systems. The Nisshinbo NL9620 supports a wide supply voltage range from ±2.3V to ±18V, and offers a gain range from 1 to 10,000, configurable via external resistors. With a high common-mode rejection ratio (CMRR) of 110dB (minimum) and rail-to-rail output, the NL9620 amplifiers deliver robust performance even in noisy environments. Available in a VSP-8-AF or an EMP-8-AN package, combined with low power consumption, further enhances suitability for precision analog front-end designs in space-constrained and power-sensitive applications.
