ADC1025 - 10-Bit uP Compatible A/D Converter

General Description

The ADC1005 and ADC1025 are CMOS 10-bit successive approximation AID converters.

The 20-pin ADC1005 outputs 10-bit data in a two-byte format for interface with B-bit microprocessors.

The 24-pin ADC1025 outputs 10 bits in parallel and is intended for 16-bit data buses or stand-alone applications.

Key Features

  • II Easy interface to all microprocessors II Differential analog voltage inputs II Operates ratiometrically or with 5 Voc voltage reference or analog span adjusted voltage reference II OV to 5V analog input voltage range with single 5V supply II On-chip clock generator II TLLl.

~National ~ Semiconductor ADC10051ADC1025 10-Bit ILP Compatible AID Converters General Description The ADC1005 and ADC1025 are CMOS 10-bit successive approximation AID converters. The 20-pin ADC1005 outputs 10-bit data in a two-byte format for interface with B-bit microprocessors. The 24-pin ADC1025 outputs 10 bits in parallel and is intended for 16-bit data buses or stand-alone applications. Both A-to-Ds have differential inputs to permit rejection of common-mode signals, allow the analog input range to be offset, and also to permit the conversion of signals not referred to ground. In addition, the reference voltage can be adjusted, allowing smaller voltage spans to be measured with 10-bit resolution.
