IC ADC 12BIT SAR 24DIP 12 Bit Analog to Digital Converter 1 Input 1 SAR 24-PDIP

Single Channel Single ADC SAR 100ksps 12-bit Serial 24-Pin PDIP N Tube

The AD7853/AD7853L are high speed, low power, 12-bit ADCs that operate from a single 3 V or 5 V power supply, the AD7853 being optimized for speed and the AD7853L for low power. The ADC powers up with a set of default conditions at which time it can be operated as a read-only ADC. The ADC contains self-calibration and system-calibration options to ensure accurate operation over time and temperature and have a number of power-down options for low power applications. The part powers up with a set of default conditions and can operate as a read only ADC. The AD7853 is capable of 200 kHz throughput rate while the AD7853L is capable of 100 kHz throughput rate. The input track-and-hold acquires a signal in 500 ns and features a pseudo-differential sampling scheme. The AD7853/AD7853L voltage range is 0 to VREF with both straight binary and 2s complement output coding. Input signal range is to the supply, and the part is capable of converting full power signals to 100 kHz. CMOS construction ensures low power dissipation of typically 5.4 mW for normal operation and 3.6 µW in power-down mode. The part is available in 24-pin, 0.3 inch wide dual-in-line package (DIP), 24-lead small outline (SOIC) and 24-lead small shrink outline (SSOP) packages.
