ADI releases 4-channel, 16-bit, 125-MSPS ADC for medical and communication sys

Analog Devices Inc. (ADI) has announced the addition of a 4-channel high-speed Analog to Digital converter to its product portfolio. The AD9653 A/D converter was designed for medical imaging and communications applications where the combination of high channel density, low power and small size provide systems engineers with greater design flexibility and lower per-channel cost for data conversion.

The AD9653 16-bit quad A/D converter supports the higher channel densities of MRI (magnetic resonance imaging) systems, medical ultrasound and other high-end imaging applications, such as industrial visual inspection systems and non-destructive ultrasound. It is offered in a non-magnetic package and can be used safely within the magnetic field of an MRI system. This allows the converter to be placed closer to the signal of interest, which can increase the image quality and throughput.

The device can be used in MIMO- (multiple-input, multiple-output) based radios, 3G infrastructure equipment and other wireless communications applications. They are suitable for femto and pico-cell basestation designs.

Features
1. Power: 164 mW per channel at 125 MSPS with scalable power option
2. Dynamic range:
a. SNR = 76.5 dBFS @ 70 MHz (VREF = 1.0 V)
b. SNR = 77.5 dBFS @ 70 MHz (VREF = 1.3 V)
c. SFDR = 90 dBc (to Nyquist)

3. 650-MHz full power analog bandwidth
4. Serial LVDS digital output (ANSI-644 or reduced power mode similar to IEEE-1596.3)
5. Package outline: 7 x 7 mm, 48-pin LFCSP

AD9653-125 is now available in full production quantities and the price is $250.0 each in 1,000 quantities.
