Texas Instruments PGA5807ARGCR

Description
The PGA5807A is an 8-channel, high-bandwidth analog front-end (AFE) that operates on a single 3.3-V analog supply. It supports high-bandwidth input frequencies with a total power of 60 mW per channel. The device consists of a low-noise amplifier (LNA), a programmable gain amplifier (PGA), and a programmable low-pass filter (LPF). The LNA has a fixed 12-dB gain and supports a maximum linear input range of 500 mVpp. The PGA provides gain options from 0 dB to 18 dB in 3-dB gain steps, which can be programmed using either the serial interface or external pins. The PGA5807A integrates an antialiasing filter in the form of an LPF to reduce noise. It is available in a 9-mm x 9-mm QFN-64 package and is specified for operation over the -40°C to 85°C temperature range.
