Description

The Intersil HI-7152 is a high speed 10-bit A/D converter which uses a Two-Step, Flash algorithm to achieve throughput rates of 200kHz. A unique switched capacitor technique allows a new input voltage to be sampled while a conversion is taking place.

Internal high speed CMOS buffers at both the analog and reference inputs simplify external drive requirements. A Track and Hold amplifier is included on the chip, consisting of two high speed amplifiers and an internal hold capacitor. Microprocessor bus interfacing is simplified by the use of standard Chip Select, Read, and Write control signals. The digital three-state outputs of HI-7152 are byte organized for interfacing the either 8-bit or 16-bit systems. An out-of-range pin, together with the MSB, can be used to indicate an underrange or over-range condition.

The HI-7152 operates with ±5V supplies. A single +2.5V reference is required to provide a bipolar input range from -2.5V to +2.5V.
