Demo Board for LTC2338-18 - 18-Bit, 1Msps, Fully Differential SAR ADC with True Bipolar +/-10V Inputs
The LTC®2338/LTC2337/LTC2336/LTC2328/LTC2327/ LTC2326 are true bipolar, low power, low noise ADCs with serial outputs that can operate from a single 5V supply. The following text refers to the LTC2338-18 but applies to all parts in the family, the only difference being the maximum sample rates and the number of bits. The LTC2338-18 supports a ±20.48V fully differential input range with a 100dB SNR, consumes only 50mW and achieves ±4LSB INL max with no missing codes at 18 bits. The DC1908A demonstrates the DC and AC performance of the LTC2338-18 in conjunction with the DC590 QuikEval™ and DC718 PScope™ data collection boards.
The LTC®2338-18 is a low noise, high speed 18-bit successive approximation register (SAR) ADC with fully differential inputs. Operating from a single 5V supply, the LTC2338-18 has a ±10.24V true bipolar input range, making it ideal for high voltage applications which require a wide dynamic range. The LTC2338-18 achieves ±4LSB INL maximum, no missing codes at 18-bits with 100dB SNR.
