ICM7377B/7357B/7337B is a quad 12/10/8-bit voltage output DACs with serial interface and adjustable output gain. They feature wide output voltage swing, low power consumption, and adjustable gain. They are suitable for battery-powered applications, industrial process control, digital gain and offset adjustment, etc.
The ICM7377B, ICM7357B, and ICM7337B are quad voltage output DACs with 12-bit, 10-bit, and 8-bit resolution respectively. They feature adjustable output gain, serial interface compatibility with SPI/QSPI and Microwire, and are packaged in a 20-lead QSOP. The devices operate from 2.7V to 5.5V and include on-board reference outputs. Each DAC has a double-buffered digital input and supports daisy-chaining via serial data output.
