SBAS632 –OCTOBER 2013

8-Channel, High-Bandwidth, Analog Front-End

Check for Samples: PGA5807A

FEATURES

APPLICATIONS

•

8-Channel Complete AFE:

•

Data Acquisition Front Ends

Ultrasound Imaging

–

LNA, PGA, and LPF

Full-Channel Gain: 12 dB to 30 dB

Input-Referred Noise: 2.1 nV/√Hz

DESCRIPTION

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

•

LNA:

–

Gain: 12 dB

Fully Differential

Wide Input Common-Mode Support:

2.1 ± 200 mV

–

Maximum Linear Input Range: 500 mV_PP

•

PGA Gain: 0 dB to 18 dB

–

With 3-dB Gain Steps

of 500 mV_PP

Programmable via Either Serial Interface or

External Pins

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.

•

Maximum Total Channel Gain: 30 dB

Programmable LPF:

–

Corner Frequency: 75 MHz, 60 MHz

Power (Full-Chain):

60 mW per Channel

•

•

Fast and Consistent Overload Recovery

Small Package: 9-mm × 9-mm QFN-64
