SP973T8

www.DataSheet4U.com DS2465 - 2.3 SP973T8 30MHz 8-BIT FLASH ADC (TTL/CMOS OUTPUTS) The SP973T8 is a wideband, full flash analog-to-digital converter that requires no preceding sample and hold. The device contains a full 8-bit D-type latch which ensures that the 8 TTL/CMOS outputs are accurately registered and have a good data valid time at high clock speeds. Operating from a single +5 volt supply the device is capable of conversion rates well in excess of 30MHz and its wideband input allows signals with frequencies up to the Nyquist limit to be digitised with high accuracy. An internal bandgap voltage regulator gives low DC drift over a wide operating temperature range. The SP973T8 is designed for applications where power consumption and package size is at a premium.
