The device uses a resistor-string architecture: each DAC channel consists of a 256-tap resistor divider between VDD and GND, with the output buffer providing low output impedance (1 ohm typical) and the ability to source\/sink 5mA. The VDD supply also serves as the reference voltage, so the output accuracy is directly proportional to VDD accuracy. The output voltage for a given code is VOUT = (CODE \/ 256) x VDD, where CODE ranges from 0 to 255. The I2C interface supports standard mode (100kHz), fast mode (400kHz), and high-speed mode (3.4MHz). The A0 pin allows two devices to share the same I2C bus by providing two possible addresses (0x98 or 0x9A base address). The device supports three update modes: (1) Write to individual channel - update one DAC immediately; (2) Write to all channels - update all three DACs simultaneously (for multi-channel control that requires synchronized outputs); (3) Power-down mode - each channel can be independently powered down to 1uA, with the output connected to GND through a 100k-ohm or 1M-ohm resistor. The power-on reset sets all DAC outputs to 0V (code 0x00). The settling time is 8us to +\/-0.5 LSB for a full-scale step. The TSSOP-14 package is 5.0 x 4.4mm. The -IPWR suffix specifies industrial temperature (-40C to +105C), TSSOP-14 tape-and-reel.","pin_description":"
