FEATURES
GENERAL DESCRIPTION
The low-cost ADS-30639 is a dual 14-bit, 6.4MHz sampling
A/D converter. This device accurately samples full-scale input
signals up to Nyquist frequencies with no missing codes. The
dynamic performance of the ADS-30639 has been optimized to
achieve a signal-to-noise ratio (SNR) of 78dB and a total
harmonic distortion (THD) of –80dB. Each channel is
completely independant allowing operation with independant
analog inputs and start convert signals.
Packaged in a miniature 28-pin DDIP, the functionally complete
ADS-30639 contains two individual fast-settling sample-hold
amplifiers and subranging A/D converters, along with an
internal reference, timing/control logic, and error-correction
circuitry. Digital input and output levels are TTL. The ADS-
30639 only requires the rising edge of the start convert pulse
to operate.
Requiring only ±5V and +15V supplies, the ADS-30639
dissipates 1.7 Watts. The device is offered with a bipolar
(±2.0V) analog input range. Model is available for use in –55
to +125°C operating temperature range. A proprietary, auto-
