●PGA5807A

●, 8-channel, high-bandwidth, analog front end (AFE). The device functions on a single 3.3-V analog supply and supports input frequencies up to 25 MHz with a total power of 60mW per channel. The PGA5807A 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 (differential amplifier with dc input coupling) and supports a maximum linear input range of 500 mVPP. The device provides gain options from 0 dB to 18 dB, in 3-dB gain steps. This 18-dB PGA gain range 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.

●The device is available in a very small, 9-mm × 9-mm QFN-16 package and is specified for operation over the –40°C to +85°C temperature range.
