AD6640

PRODUCT DESCRIPTION

The AD6640 is a high speed, high performance, low power,

monolithic 12-bit analog-to-digital converter. All necessary

functions, including track-and-hold (T/H) and reference are

included on-chip to provide a complete conversion solution.

The AD6640 runs on a single +5 V supply and provides CMOS-

compatible digital outputs at 65 MSPS.

Specifically designed to address the needs of multichannel,

multimode receivers, the AD6640 maintains 80 dB spurious-

free dynamic range (SFDR) over a bandwidth of 25 MHz.

Noise performance is also exceptional; typical signal-to-noise

ratio is 68 dB.

The AD6640 is built on Analog Devices’ high speed complemen-

tary bipolar process (XFCB) and uses an innovative multipass

architecture. Units are packaged in a 44-terminal Plastic Thin

Quad Flatpack (TQFP) specified from –40

°C to +85°C.

PRODUCT HIGHLIGHTS

1. Guaranteed sample rate is 65 MSPS.

2. Fully differential analog input stage specified for frequencies

up to 70 MHz; enables “IF Sampling.”

3. Low power dissipation: 710 mW off a single +5 V supply.

4. Digital outputs may be run on +3.3 V supply for easy inter-

face to digital ASICs.

5. Complete Solution: reference and track-and-hold.

6. Packaged in small, surface mount, plastic 44-terminal TQFP.
