PGA5807RGCR

Analog Front End (AFE) Overview

The PGA5807RGCR is an 8-channel, high-bandwidth analog front-end (AFE) from Texas Instruments. It integrates a low-noise amplifier (LNA), programmable gain amplifier (PGA), and programmable low-pass filter (LPF). The device operates on a single 3.3-V analog supply with a total power consumption of 60 mW per channel. Key electrical parameters include an input-referred noise of 2.1 nV/√Hz, a maximum linear input range of 500 mVPP, and a total channel gain ranging from 12 dB to 30 dB. The LPF offers selectable corner frequencies of 75 MHz or 60 MHz. It is housed in a 9-mm × 9-mm QFN-64 package.

Analog Front End (AFE) Feature Summary

• 8-Channel AFE with LNA (12 dB fixed gain), PGA (0–18 dB), and LPF
• Input-referred noise of 2.1 nV/√Hz at 25 MHz
• Programmable gain via serial interface or external pins in 3-dB steps
• Selectable LPF corner frequency: 75 MHz (default) or 60 MHz

Analog Front End (AFE) Applications

• Data acquisition front ends
• Ultrasound imaging systems

Analog Front End (AFE) Procurement Notes

Verify the component status as active for new designs. Confirm the package type is VQFN (RGC) with 64 pins and the standard packaging quantity is 2,000 units per reel. Ensure compatibility with the specified operating temperature range of –40°C to +85°C and the required 3.3-V analog supply voltage.

Analog Front End (AFE) Selection Notes

Select this part when an integrated solution for multi-channel signal conditioning is required. It supports both direct and capacitive input coupling. The device allows gain configuration through either the serial interface (SEN, SCLK, SDATA) or parallel GAIN pins. Ensure the system design accommodates the 2.1-V input common-mode voltage and the 0.95-V output common-mode voltage.

Analog Front End (AFE) Part Context

The PGA5807 is part of the PGA580 family of analog front-ends. The RGCR suffix indicates the RGC package variant (QFN-64) supplied in a tape-and-reel format. This specific model is designed for high-frequency applications requiring low noise and precise gain control across multiple channels simultaneously.
