CSMC 0.13um 8-Bit 4-Input 200k SAR ADC
This analog-to-digital converter uses Successive Approximation Register (SAR) architecture to achieve 8-bit resolution.
Overview
This analog-to-digital converter uses Successive Approximation Register (SAR) architecture to achieve 8-bit resolution. The IP includes 4-1 MUX and a core internal SAR ADC which consists of sample/hold circuits, a capacitive DAC, a comparator and logic control circuits. It also has in-chip resistor divider and keypad interrupt generator. The converter has flexible control logic, and could be easily embedded in a complex system.
External reference is needed. In addition, the reference voltage input will be adjusted to allow encoding smaller analog voltage spanning to the full 8bit resolution. The ADC has the maximum speed mode – 200K - working in lower speed could save some power. And it supports two running modes: free running and single running. In single running mode, SAR will switch to power down mode automatically so as to save power.
The ADC is especially suitable to act as Battery Monitor, or for Temperature Measurement and Key Pad Detection. It is also suitable for other Battery-Operated Systems and Data Acquisitions.
