• 8-Channel Complete Analog Front-End:

The AFE5804 is a complete analog front-end device

specifically designed for ultrasound systems that

–

LNA, VCA, PGA, LPF, and ADC

require low power and small size.

• Mode Control for Power/Noise Optimization:

The AFE5804 consists of eight channels, including a

–

Low Noise (Full-Channel):

low-noise

amplifier

(LNA),

voltage-controlled

0.89nV/

√Hz (TGC Mode I)

attenuator

(VCA),

programmable

gain

amplifier

1.23nV/

√Hz (TGC Mode II)

(PGA),

low-pass

filter

(LPF),

and

a

12-bit

1.03nV/

√Hz (PW Mode)

analog-to-digital converter (ADC) with low voltage

–

Ultra-Low Power:

differential signaling (LVDS) data outputs.

101mW/Channel (TGC Mode II)

The LNA gain is set for 20dB gain and has excellent

65mW/Channel (CW Mode)

noise and signal handling capabilities, including fast

• Low-Noise Pre-Amp (LNA):

overload recovery. VCA gain can vary over a 46dB

–

0.75nV/

√Hz

range with a 0V to 1.2V control voltage common to all

channels of the AFE5804.

–

20dB Fixed Gain

The PGA can be programmed for gains of 20dB,

–

280mVPP Linear Input Range

25dB, 27dB, and 30dB. The internal low-pass filter

• Variable-Gain Amplifier:

can also be programmed to 12.5MHz or 17MHz.

–

Gain Control Range: 46dB

The LVDS outputs of the ADC reduce the number of

• PGA Gain Settings: 20dB, 25dB, 27dB, 30dB

interface lines to an ASIC or FPGA, thereby enabling

• Low-Pass Filter:

the high system integration densities desired for

portable systems. The ADC can either be operated

–

Selectable BW: 12.5MHz, 17MHz

with internal or external references. The ADC also

–

2nd-Order, Bessel

features a signal-to-noise ratio (SNR) enhancement

• Gain Error: ±0.5dB

mode that can be useful at high gains.

• Channel Matching: ±0.25dB
