Analog Devices’ Dual 14-bit A/D Converter Reduces Power and Size
in
Communications, Instrumentation, Test and Measurement Applications |
July 10, 2012
Press Release 
NORWOOD, Mass.--( BUSINESS WIRE)-- Analog Devices, Inc. ( ADI),
the data converter market share leader* and a data conversion and signal processing technology innovator for more
than 47 years, today introduced a two-channel, high-performance 14-bit, 125-MSPS A/D converter that reduces total power consumption by 22 percent over competing solutions. In
addition to delivering high speed and wide dynamic range at lower power, the cost-effective and functionally
flexible AD9645 A/D converter is available in a 5-mm ×
5-mm package, which represents a 30 percent space savings over the nearest competitor. The new converter meets the
performance and size requirements of the latest 3G and 4G multi-standard cellular infrastructure equipment, such
as CDMA2000, WB-CDMA, LTE, TD-SCDMA and multi-carrier GSM. Other key applications include battery-powered,
hand-held instruments, scopes and portable medical devices.
The dual
AD9645 A/D converter consumes only 122 mW/channel at 125 MSPS (mega samples per second) and features excellent
SFDR (spurious-free dynamic range) performance of 91 dBc at 70 MHz. With an IF sampling range of up to of 200 MHz,
the device is designed for use in multi-mode digital receiver architectures. A pin-compatible dual 12-bit version,
the AD9635, is also available, enabling an easy migration path between 12-bit and 14-bit converters with sampling
rates from 20 MSPS to 125 MSPS.

The AD9645 dual A/D converter features a multi-stage, differential pipelined architecture with integrated
output-error-correction logic. The AD9645 is available in a 32-lead RoHS-compliant LFCSP and is specified over the
industrial temperature range of –40°C to +85°C. The dual A/D converter features a space-saving serial 1.8-V LVDS
digital output with two lanes per channel.
