MAXIM INTEGRATED PRODUCTS  MAX5854ETL+  数模转换器, 电流输出, 10 bit, 并行, 2.7V 至 3.6V, TQFN, 40 引脚

The is a dual, 10bit, 165Msps, current output DAC in 40 pin TQFN package. The device integrates two 10bit DAC cores and a 1.24V reference. The MAX5854 supports single ended and differential modes of operation and can operate in interleaved data mode to reduce the I/O pin count. The MAX5854 features digital control of channel gain matching to within ±0.4dB in sixteen 0.05dB steps. Channel matching improves sideband suppression in analogue quadrature modulation applications. The on-chip 1.24V bandgap reference includes a control amplifier that allows external full-scale adjustments of both channels through a single resistor. The internal reference can be disabled and an external reference can be applied for high-accuracy applications. The MAX5854 features full-scale current outputs of 2mA to 20mA. The DAC supports three modes of power-control operation of normal, low power standby and complete power down. In power-down mode, the operating current is reduced to 1µA.
