Linear Technology launched three families of low power 16-bit, 25Msps to 125Msps analog-to-digital converters (ADCs) that it claims dissipate approximately half the power of competing 16-bit products.
The LTC2165 and LTC2185 families are single- and two-channel simultaneous sampling parallel ADCs , respectively, offering a choice of full-rate CMOS, or double data rate (DDR) CMOS/LVDS digital outputs with programmable digital output timing, programmable LVDS output current and optional LVDS output termination. The LTC2195 family includes two-channel, simultaneous sampling ADCs with serial LVDS outputs. Each ADC family offers a choice of pin-compatible converters, sampling from 25Msps up to 125Msps and optimized for the lowest power dissipation at the rated speed.
Applications include handheld test and instrumentation , radar/LIDAR, portable medical imaging, PET/SPECT scanners, smart antenna systems and a variety of low-power communication systems .
