The DS4432U+T&R from Maxim\/ADI is an I2C 8-bit dual current-output DAC. Each channel sources or sinks up to 200uA. 8-bit resolution with 7-bit magnitude and 1-bit direction. I2C interface. Power-on reset to zero. MSOP-8 compact package. For bias adjustment and offset correction in analog circuits.<\/p>\n

The DS4432 provides two independent 8-bit current DACs. Each 8-bit value consists of a 7-bit magnitude and a 1-bit sign bit that determines current direction (source or sink). The full-scale current is set by an external resistor on the FS pin (IFS = 0.793V \/ RFS). The DAC output current is then IOUT = (Code\/127) x IFS x Direction. This bidirectional capability makes the DS4432 ideal for offset trimming – it can add or subtract a small current to null offsets in analog circuits. I2C interface allows software-controlled adjustment. Power-on reset sets both outputs to zero current.<\/p>\n
