Descripción de PGA5807A
The PGA5807A is an 8-channel, high-bandwidth, analog front-end (AFE). The device functions on a single 3.3-V analog supply. The device supports high-bandwidth input frequencies with a total power of 60 mW 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 (the differential amplifier supports both direct and capacitive 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 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-64 package and is specified for operation over the –40°C to +85°C temperature range.
