ANALOG DEVICES’ DUAL 14-BIT A/D CONVERTER REDUCES POWER AND SIZE IN COMMUNICATIONS, INSTRUMENTATION, TEST AND MEASUREMENT APPLICATIONS

Analog Devices’ Dual 14-bit A/D Converter Reduces Power and Size in Communications, Instrumentation,

Norwood, MA (07/10/2012) - 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.
