ADC1005

Contents

The ADC1005 is a CMOS 10-bit successive approximation A/D converter. The 20-pin ADC1005 outputs 10-bit data in a two-byte format for interface with 8-bit microprocessors.

The ADC1005 has 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.

• Easy interface to all microprocessors
• Differential analog voltage inputs

• Operates ratiometrically or with 5 V_DC voltage reference or analog span adjusted voltage reference
• 0V to 5V analog input voltage range with single 5V supply
• On-chip clock generator
• TLL/MOS input/output compatible
• 0.3" standard width 20-pin DIP
