MCP3204/3208 is a 12-bit successive approximation analog-to-digital (A/D) converter with on-chip sample and hold circuitry. MCP3204 can be programmed to provide 2 pseudo differential input pairs or 4 single-ended inputs. MCP3208 can be programmed to provide 4 differential input pairs or 8 single-ended inputs. Differential nonlinearity (DNL) specification is ±1 LSB, integral nonlinearity (INL) is ±1 LSB (MCP3204/3208-B) and ±2 LSB (MCP3204/3208-C). It uses a simple serial port compatible with SPI protocol to communicate with the device. The device's conversion rate can reach 100 ksps. MCP3204/3208 devices have a wide voltage operating range of 2.7V to 5.5V. Its low current design consumes only 500 nA and 320 µA of typical standby current and working current.
The MCP3204 and MCP3208 are 12‑bit SAR ADCs with SPI serial interface (mode 0.0 and 1.1). They operate from 2.7 V to 5.5 V and provide either 4 single‑ended inputs (MCP3204) or 8 single‑ended inputs (MCP3208), with optional differential input configurations. Typical standby current is 500 nA, and active current is as low as 320 nA.
These devices are offered in PDIP, SOIC, and TSSOP packages (14‑lead for MCP3204, 16‑lead for MCP3208). Performance includes up to 100 ksps sampling at 5 V supply (50 ksps at 2.7 V), -40 °C to +85 °C operating temperature, and low DNL/INL errors. This manual is written in Chinese.
