PGA870 Description
The PGA870 is a wideband programmable-gain amplifier (PGA) for high-speed signal chain and data acquisition systems. The PGA870 has been optimized to provide high bandwidth, low distortion, and low noise, making it ideally suited as a 14-bit analog-to-digital converter (ADC) driver for wireless base station signal chain applications. The wide gain range of 11.5 dB to +20 dB can be adjusted in 0.5-dB gain steps...
