The ADS-424SM is a 12-bit, 250kSPS multi-, 4-Channels SAR Analog to Digital converter housed in a 16-pin plastic TSSOP package. It is the best choice for all military, airborne, and aerospace applications that can utilize a low cost Commercial Off-The-Shelf (COTS) component such as the ADS-424SM.
Each unit features no missing codes, ± 0.5 LSB of Differential Non-Linearity, ± 0.5 of Integral Non-Linearity and is 100 percent tested for performance over the tempaerature of -55 to +1250C. The ADS-924SM requires only one supply voltage for operation ranging from +2.7 to 5.25 Volts and consumes only 3 mA of supply current. It has a sleep mode feature that consumes only 8 uA of current. It is the ideal selection for low power and battery operated multi-channel Data Acquisition Systems.
The ADS-424SM offers a unique architecture that includes a sample-hold, a successive approximation A/D, and an SPI compatible serial interface. It features an excellent signal-to noise ratio (SNR) of 73dB and a total harmonic distortion (THD) of -85dB, which makes the ADS-924SM the ideal choice for both time domain (imaging, telemetry, process control) and frequency-domain (radar, telecommunications, spectrum analysis) applications.
