Audio line receivers
Differential-input amplifiers integrated with high-performance op amps and precision well-matched thin-film resistors
Our series of audio line recievers are designed to provide best in class common-mode rejection ratio using our precision matched resistors. These differential line recievers are built to optimize noise and THD+N to provide a clear and crisp audio sound. Designed for both industrial and audio applications.
Importance of Input Bias Current Return Paths in Instrumentation Amplifier Apps
A typical application problem when designing with an instrumentation amplifier is neglectng a dc return path to ground in both ac and dc applications. This article discusses how to simply solve this common problem.
On-Chip Thin Film Resistors Enable High-Performance Audio Circuitry
In audio products requiring small size, low distortion, or excellent matching, on-chip thin-film resistors (TFRs) can provide superior performance compared to discrete resistors.
SPICE model accuracy, part 1: common-mode rejection ratio
This blog provides recommended test circuits for many of the most critical op amp parameters, starting with common-mode rejection ratio (CMRR).
