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