LTC2392-16 16-Bit, 500ksps SAR ADC with 94dB SNR
Features Description
n
500ksps Throughput Rate
The LTC®2392-16 is a low noise, high speed 16-bit suc- n
±2LSB INL (Max)
cessive approximation register (SAR) ADC. Operating n
Guaranteed 16-Bit No Missing Codes
from a single 5V supply, the LTC2392-16 supports a large n
94dB SNR (Typ) at fIN = 20kHz
±4.096V fully differential input range, making it ideal for n Guaranteed Operation to 125°C high performance applications which require maximum n Single 5V Supply dynamic range. The LTC2392-16 achieves ±2LSB INL n 1.8V to 5V I/O Voltages max, no missing codes at 16-bits and 94dB SNR (typ). n 110mW Power Dissipation The LTC2392-16 includes a precision internal reference n ±4.096V Differential Input Range with a guaranteed 0.5% initial accuracy and a ±20ppm/°C n Internal Reference (20ppm/°C Max) (max) temperature coefficient. Fast 500ksps throughput n No Pipeline Delay, No Cycle Latency with no cycle latency in both parallel and serial interface n Parallel and Serial Interface modes makes the LTC2392-16 ideally suited for a wide n Internal Conversion Clock variety of high speed applications. An internal oscillator n 48-Lead 7mm × 7mm LQFP and QFN Packages sets the conversion time, easing external timing con- siderations. The LTC2392-16 dissipates only 110mW at
