GENERAL DESCRIPTION

The low-cost ADS-943 is a 14-bit, 3MHz sampling A/D converter optimized to meet the demanding dynamic-range and sampling-rate requirements of contemporary digital telecommunications applications. The ADS-943s outstanding dynamic performance is evidenced by a peak harmonic specification of –83dB and a signal-to-noise ratio (SNR) of 79dB. Additionally, the ADS-943 easily achieves the 2.2MHz minimum sampling rate required by digital receivers in certain ADSL, HDSL and ATM applications. The ADS-943 also addresses size and power constraints normally associated with these types of applications. This device requires just ±5V supplies, dissipates 1.7 Watts, and is packaged in a very small 24-pin DDIP.
