Overview

The 3PD9708(E) offers exceptional AC and DC performance while supporting update rates up to 125 MSPS. Its flexible single-supply operating range from +2.7 V to +5.5 V and low power dissipation are well suited for portable and low-power applications. Its power dissipation can be reduced to 45 mW, without a significant degradation in performance, by lowering the full-scale current output. In addition, a power-down mode reduces the standby power dissipation to approximately 20 mW.

The 3PD9708(E) is manufactured on an advanced CMOS process. A segmented current source architecture is combined with a proprietary switching technique to reduce spurious components and enhance dynamic performance. The edge-triggered input latches, and a temperaturecompensated bandgap reference is integrated to provide a complete monolithic DAC solution. Flexible supply options support 3-V and 5-V CMOS logic families.

The 3PD9708(E) is a current-output DAC with a nominal full-scale output current of 20 mA and an output impedance of > 100 kΏ.

Differential current outputs are provided to support singleended or differential applications. The current outputs may be directly tied to an output resistor to provide two complementary, single-ended voltage outputs. The output voltage compliance range is 1.25 V. The 3PD9708(E) contains a 1.1-V on-chip reference and a reference control amplifier, which allows the full-scale output current to be simply set by a single resistor. The 3PD9708(E) can be driven by a variety of external reference voltages.

The full-scale current of the 3PD9708(E) can be adjusted over the range from 2 mA to 20 mA without any degradation in dynamic performance. Thus, the 3PD9708(E) may operate at reduced power levels or be adjusted over a 20-dB range to provide additional gain ranging capabilities. The 3PD9708(E) is available in the TSSOP28 package. It is specified for operation over the industrial temperature range.
