LTC2335-16 16-Bit, 1Msps 8-Channel Differential 10.24V Input SoftSpan ADC with Wide Input Common Mode Range Fea T Descrip T n 1Msps Throughput The LTC 2335-16 is a 16-bit, low noise 8-channel multi- n 1LSB INL (Maximum) plexed successive approximation register (SAR) ADC with n differential, wide common mode range inputs. Operating Guaranteed 16-Bit, No Missing Codes n from a 5V low voltage supply, flexible high voltage supplies, Differential, Wide Common Mode Range Inputs TM n and using the internal reference and buffer, this SoftSpan 8-Channel Multiplexer with SoftSpan Input Ranges: ADC can be configured on a conversion-by-conversion 10.24V, 0V to 10.24V, 5.12V, 0V to 5.12V basis to accept 10.24V, 0V to 10.24V, 5.12V, or 0V to 12.5V, 0V to 12.5V, 6.25V, 0V to 6.25V 5.12V signals on any channel. Alternately, the ADC may n 94.4dB Single-Conversion SNR (Typical) be programmed to cycle through a sequence of channels n 109dB THD (Typical) at f = 2kHz IN and ranges without further user intervention. n 118dB CMRR, 125dB Active Crosstalk (Typical) n Rail-to-Rail Input Overdrive Tolerance The wide input common mode range and 118dB CMRR of n Programmable Sequencer with No-Latency Control the LTC2335-16 analog inputs allow the ADC to directly n Guaranteed Operation to 125C digitize a variety of signals, simplifying signal chain de- n Integrated Reference and Buffer (4.096V) sign. This input signal flexibility, combined with 1LSB n SPI CMOS (1.8V to 5V) and LVDS Serial I/O INL, no missing codes at 16 bits, and 94.4dB SNR, makes n No Pipeline Delay, No Cycle Latency the LTC2335-16 an ideal choice for many high voltage n 180mW Power Dissipation (Typical) applications requiring wide dynamic range. n 48-Lead (7mm 7mm) LQFP Package The LTC2335-16 supports pin-selectable SPI CMOS (1.8V to 5V) and LVDS serial interfaces. a T L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks and SoftSpan is a trademark of Linear Technology Corporation.
