LTC2152-12/ LTC2151-12/LTC2150-12 Single 12-Bit 250Msps/ 210Msps/170Msps ADCs
FEATURES DESCRIPTION
n 68.5dB SNR The LTC®2152-12/LTC2151-12/LTC2150-12 are a family n 90dB SFDR of 250Msps/210Msps/170Msps 12-bit A/D converters n Low Power: 347mW/333mW/306mW Total designed for digitizing high frequency, wide dynamic range n Single 1.8V Supply signals. They are perfect for demanding communications n DDR LVDS Outputs applications with AC performance that includes 68.5dB n Easy-to-Drive 1.5VP-P Input Range SNR and 90dB spurious free dynamic range (SFDR). The n 1.25GHz Full Power Bandwidth S/H 1.25GHz input bandwidth allows the ADC to undersample high input frequencies with good performance. The latency n Optional Clock Duty Cycle Stabilizer is only six clock cycles. n Low Power Sleep and Nap Modes n Serial SPI Port for Configuration DC specs include ±0.26LSB INL (typ), ±0.16LSB DNL (typ) n Pin-Compatible 14-Bit Versions and no missing codes over temperature. The transition n 40-Lead (6mm × 6mm) QFN Package noise is 0.54LSBRMS.
APPLICATIONS
The digital outputs are double-data rate (DDR) LVDS. n Communications The ENC+ and ENC– inputs can be driven differentially with n Cellular Basestations a sine wave, PECL, LVDS, TTL, or CMOS inputs. An optional n Software Defined Radios clock duty cycle stabilizer allows high performance at full speed for a wide range of clock duty cycles. n Medical Imaging n High Definition Video L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
