MCP3204-CI/P

模数转换器 - ADC 12-bit SPI 4 Chl

2.7V 4-Channel/8-Channel 12-Bit A/D Converters  with SPI™ Serial Interface

Description MCP3204-CI/P

The Microchip Technology Inc. MCP3204/3208 devices are successive approximation 12-bit Analogto-Digital (A/D) Converters with on-board sample and hold circuitry. The MCP3204 is programmable to provide two pseudo-differential input pairs or four singleended inputs. The MCP3208 is programmable to provide four pseudo-differential input pairs or eight singleended inputs. Differential Nonlinearity (DNL) is specified at ±1 LSB, while Integral Nonlinearity (INL) is offered in ±1 LSB (MCP3204/3208-B) and ±2 LSB (MCP3204/3208-C) versions.
