LTC2257-12 - Ultralow Power 1.8V ADCs

Download the LTC2257-12 datasheet PDF. This datasheet also covers the LTC2256-12 variant, as both devices belong to the same ultralow power 1.8v adcs family and are provided as variant models within a single manufacturer datasheet.

Description

The LTC®2258-12/LTC2257-12/LTC2256-12 are sampling 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 71.1dB SNR and 88dB spurious free dynamic range (SFDR).

Features

  • n 71.1dB SNR n 88dB SFDR n Low Power: 79mW/47mW/34mW n Single 1.8V Supply n CMOS, DDR CMOS or DDR LVDS Outputs n Selectable Input Ranges: 1VP-P to 2VP-P n 800MHz Full-Power Bandwidth S/H n Optional Data Output Randomizer n Optional Clock Duty Cycle Stabilizer n Shutdown and Nap Modes n Serial SPI Port for Configuration n Pin Compatible 14-Bit and 12-Bit Versions n 40-Pin (6mm × 6mm) QFN Package.
