FEATURES
16-bit resolution 1MHz sampling rate Functionally complete No missing codes over full HI-REL temperature range Edge-triggered ±5V supplies, 1.85 Watts Small, 40-pin, ceramic TDIP 87dB SNR, –89dB THD Ideal for both time and frequency-domain applications PRODUCT OVERVIEW The low-cost ADS-931 is a 16-bit, 1MHz sampling A/D converter. Packaged in a 40-pin TDIP, the functionally complete ADS-931 contains a fast-settling sample-hold amplifier,a subranging (two-pass) A/D converter, an internal reference, timing/control logic,and error-correction circuitry.Digital input and output levels are TTL. The ADS-931 only requires the rising edge of the start convert pulse to operate. Requiring only ±5V supplies, the ADS-931 dissipates 1.85 Watts. The device is offered with a bipolar (±2.75V) analog input range or a unipolar (0 to –5.5V) input range. Models are available in commercial (0 to +70°C), industrial (–40 to +100°C), or HI-REL (–55 to +125°C) operating temperature ranges.
