Dual 16-Bit 5Msps SAR ADC
Simultaneous Sampling ADC with Wide Input Common Mode Range
The LTC
®
2323-16 is part of a family of dual simultaneous sampling, 16-, 14- and 12-bit 5Msps SAR ADCs offering a wide input
common mode range. The flexible differential inputs can digitize a wide variety of analog signals, including pseudo-differential
unipolar and bipolar signals, and signals with an arbitrary relationship to each other, with no configuration required. The low drift,
integrated precision bandgap reference with guaranteed 20ppm/°C maximum temperature coefficient and small 20mm
