AD9740ARZ

The AD9740ARZ is a 10-bit resolution, 210 MSPS update rate digital-to-analog converter (DAC) from the TxDAC family by Analog Devices. It is designed for high-performance communication and instrumentation applications requiring wideband signal generation. The device accepts parallel digital data and provides differential current outputs with a range of 2 mA to 20 mA. Key electrical characteristics include a typical settling time of 11 ns, integral nonlinearity of ±0.15 LSB, and differential nonlinearity of ±0.12 LSB. Power dissipation is 135 mW typical at 3.3 V, with a standby mode reducing consumption to 15 mW. An on-chip 1.2 V reference is included, and the interface is CMOS-compatible. The AD9740ARZ is housed in a 28-lead SOIC surface-mount package (0.295" width) and operates over the industrial temperature range of -40°C to 85°C. It is RoHS compliant and suitable for applications such as direct IF base stations, wireless local loops, digital radio links, direct digital synthesis, and instrumentation.
