Monolithic 12-bit 2 Mhz A/d Converter - Analog Devices

The AD671 is a high speed monolithic 12-bit A/D converter offering conversion rates of up to 2 MHz (500 ns conversion time). The combination of a merged high speed bipolar/CMOS process and a novel architecture results in a combination of speed and power consumption far superior to previously avail- able hybrid implementations. Additionally, the greater reliability of monolithic construction offers improved system reliability and lower costs than hybrid designs. The AD671 uses a subranging Flash conversion technique, with digital error correction for possible errors introduced in the first part of the conversion cycle. An on-chip Timing generator pro- vides strobe pulses for each of the four internal Flash cycles and assures adequate settling time for the interflash residue ampli- fier. A single ENCODE pulse is used to control the converter. The performance of the AD671 is made possible by using high speed, low noise bipolar circuitry in the linear sections and low power CMOS for the Logic sections. Analog Devices ABCMOS-1 process provides both high speed bipolar and 2-micron CMOS devices on a single chip. Laser trimmed thin-film resistors are used to provide accuracy and temperature stability. The AD671 is available in two conversion speeds and perfor- mance grades. The AD671J and K grades are specified for op- eration over the 0C to +70C temperature range. The AD671S grades are specified for operation over the 55C to +125C temperature range. All grades are available in a 0.300 inch wide 24-pin ceramic DIP. The J and K grades are also available in a 24-pin plastic DIP. By Analog Devices, Inc.
