19-1895; Rev 0; 1/01 Low-Power, Dual, 8-Bit, Voltage Output Serial DAC in 8-Pin SOT23 MAX5223 General Description The MAX5223 contains two 8-bit, buffered, voltage output digital-to-analog converters (DAC A and DAC B) in a small 8-pin SOT23 package. DAC outputs can source and sink 1mA to within 100mV of ground and VDD. The MAX5223 operates with a single +2.7V to +5.5V supply. The device uses a 3-wire serial interface, which operates at clock rates up to 25MHz and is compatible with SPI™, QSPI™,.

19-1895; Rev 0; 1/01 Low-Power, Dual, 8-Bit, Voltage Output Serial DAC in 8-Pin SOT23 MAX5223 General Description The MAX5223 contains two 8-bit, buffered, voltage output digital-to-analog converters (DAC A and DAC B) in a small 8-pin SOT23 package. DAC outputs can source and sink 1mA to within 100mV of ground and VDD. The MAX5223 operates with a single +2.7V to +5.5V supply. The device uses a 3-wire serial interface, which operates at clock rates up to 25MHz and is compatible with SPI™, QSPI™, and MICROWIRE™ interface standards. The serial input shift register is 16 bits long and consists of 8 bits of DAC input data and 8 bits for DAC selection and shutdown control. DAC registers can be loaded independently or in parallel at the positive edge of CS. The MAX5223’s ultra-low power consumption and tiny 8-pin SOT23 package make it ideal for portable and battery-powered applications. Supply current is a low 100µA and drops below 1µA in shutdown mode. In addition, the reference input is disconnected from the REF pin during shutdown, which reduces the system’s total power consumption. o Low Power Consumption 100µA Operating Current <1µA Shutdown Current o +2.7V to +5.5V Single-Supply Operation o Dual Buffered Voltage Output o Programmable Shutdown Mode o 25MHz, 3-Wire Serial Interface o SPI, QSPI, and MICROWIRE-Compatible Features o Tiny 8-Pin SOT23 Package (3mm ✕ 3mm) Ordering Information PART MAX5223EKA-T TEMP.
