SLOS729B –OCTOBER 2011–REVISED APRIL 2012

Fully Integrated, 8-Channel Ultrasound Analog Front End with

Passive CW Mixer, 0.75 nV/rtHz, 14/12-Bit, 65 MSPS, 158 mW/CH

Check for Samples: AFE5808A

FEATURES

APPLICATIONS

•

8-Channel Complete Analog Front-End

LNA, VCAT, PGA, LPF, ADC, and CW Mixer

•

Medical Ultrasound Imaging

–

Nondestructive Evaluation Equipments

•

Programmable Gain Low-Noise Amplifier

(LNA)

DESCRIPTION

The AFE5808A is a highly integrated Analog Front-

End (AFE) solution specifically designed for

ultrasound systems in which high performance and

small size are required. The AFE5808A integrates a

complete time-gain-control (TGC) imaging path and a

continuous wave Doppler (CWD) path. It also enables

users to select one of various power/noise

combinations to optimize system performance.

Therefore, the AFE5808A is a suitable ultrasound

analog front end solution not only for high-end

systems, but also for portable ones.

•

24/30 dB Programmable Gain Amplifier (PGA)

3^rdOrder Linear Phase Low-Pass Filter (LPF)

–

10, 15, 20, 30 MHz

The AFE5808A contains eight channels of voltage

controlled amplifier (VCA), 14/12-bit Analog-to-Digital

Converter (ADC), and CW mixer. The VCA includes

Low noise Amplifier (LNA), Voltage controlled

Attenuator (VCAT), Programmable Gain Amplifier

(PGA), and Low-Pass Filter (LPF). The LNA gain is

programmable to support 250 mV_PPto 1 V_PPinput

signals. Programmable active termination is also

supported by the LNA. The ultra-low noise VCAT

provides an attenuation control range of 40 dB and

improves overall low gain SNR which benefits

harmonic imaging and near field imaging. The PGA

provides gain options of 24 dB and 30 dB. Before the

ADC, a LPF can be configured as 10 MHz, 15 MHz,

20 MHz or 30 MHz to support ultrasound applications

with different frequencies. The high-performance

14bit/65 MSPS ADC in the AFE5808A achieves

77dBFS SNR. It ensures excellent SNR at low chain

gain. The ADC’s LVDS outputs enable flexible system

integration desired for miniaturized systems.

NOTE

AFE5808A is an enhanced version of AFE5808 and it is recommended for new designs.

Compared to AFE5808, it expands the cut-off frequency range of the digital high pass

filter; increases the handling capability of extreme overload signals; lowers the correlated

noise significantly when high impedance source appears.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
