LTC2313-12 12-Bit, 2.5Msps Serial Sampling ADC in TSOT FEATURES DESCRIPTION n 2.5Msps Throughput Rate The LTC 2313-12 is a 12-bit, 2.5Msps, serial sampling n No Cycle Latency A/D converter that draws only 5mA from a single 3V or n 5V supply. The LTC2313-12 contains an integrated low Guaranteed 12-Bit No Missing Codes n drift reference and reference buffer providing a low cost, Single 3V or 5V Supply n high performance (20ppm/C maximum) and space Low Noise: 73dB SNR n saving solution. The LTC2313-12 achieves outstanding Low Power: 14mW at 2.5Msps and 3V Supply n AC performance of 72.6dB SINAD and 84dB THD while Low Drift (20ppm/C Maximum) 2.048V or 4.096V sampling at 2.5Msps. The extremely high sample rate-to- Internal Reference power ratio makes the LTC2313-12 ideal for compact, low n Sleep Mode with < 1A Typical Supply Current power, high speed systems. The supply current decreases n Nap Mode with Quick Wake-Up < 1 Conversion at lower sampling rates as the device automatically enters n Separate 1.8V to 5V Digital I/O Supply nap mode after conversions. n High Speed SPI-Compatible Serial I/O n Guaranteed Operation from 40C to 125C The LTC2313-12 has a high speed SPI-compatible serial n 8-Lead TSOT-23 Package interface that supports 1.8V, 2.5V, 3V and 5V logic. The fast 2.5Msps throughput with no cycle latency makes APPLICATIONS the LTC2313-12 ideally suited for a wide variety of high n Communication Systems speed applications. n High Speed Data Acquisition Complete 14-/12-Bit Pin-Compatible SAR ADC Family n Handheld Terminal Interface 500ksps 2.5Msps 4.5Msps 5Msps n Medical Imaging 14-Bit LTC2312-14 LTC2313-14 LTC2314-14 n Uninterrupted Power Supplies 12-Bit LTC2312-12 LTC2313-12 LTC2315-12 n Battery Operated Systems Power 3V/5V 9mW/15mW 14mW/25mW 18mW/31mW 19mW/32mW n Automotive L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
