Dual 16-Bit 5Msps SAR ADC - Linear...
Transcript of Dual 16-Bit 5Msps SAR ADC - Linear...
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 20mm2 QFN package saves space in high density designs.
