12-bit, 100 MSPS+ TxDAC digital-to-analog® converter
El AD9762 es parte de la familia TxDAC de convertidores digitales a analógicos (DAC) CMOS de alto rendimiento y baja potencia con resolución de 12 bits. La familia TxDAC consta de DAC de 8, 10, 12 y 14 bits compatibles con pines optimizados para la ruta de señal de transmisión de los sistemas de comunicación. Todos los dispositivos comparten las mismas opciones de interfaz, paquetes pequeños y pines, lo que le permite subir o bajar para seleccionar el dispositivo adecuado en función del rendimiento, la resolución y el costo. El AD9762 proporciona un excelente rendimiento de CA y CC a la vez que admite velocidades de actualización de hasta 125 MSPS.
The flexible single-supply operating voltage range (2.7 V to 5.5 V) and low power consumption of the AD9762 make it ideal for portable and low power applications. By reducing the full-scale current output, the power consumption can be further reduced to only 45 mW without significant performance degradation. In addition, standby power consumption can be reduced to approximately 25 mW in power-down mode.
The AD9762 is manufactured using an advanced CMOS process. The segmented current source architecture, combined with proprietary switching technology, reduces spurious components and enhances dynamic performance. The device also integrates edge-triggered input latches and a 1.2 V temperature-compensated bandgap reference, providing a complete monolithic DAC solution. Flexible power options support +3 V and +5 V CMOS logic families.
The AD9762 is a current output DAC with a nominal full-scale output current of 20 mA and an output impedance greater than 100 kΩ.
It provides differential current outputs to support single-ended or differential applications. Matching between the two current outputs ensures enhanced dynamic performance in differential output configurations. The current output can be connected directly to an output resistor to provide two complementary single-ended voltage outputs or fed directly into the transformer. The compatible output voltage range is 1.25 V.
The on-chip reference and control amplifier are configured for maximum accuracy and flexibility. The AD9762 can be driven by an on-chip reference or by a variety of different external references. The internal control amplifier provides a wide (>10:1) adjustment range, allowing the full-scale current of the AD9762 to be regulated from 2 mA to 20 mA while maintaining excellent dynamic performance. As a result, the AD9762 can operate at low power levels or be adjusted in the 20 dB range, further providing gain range adjustment.
The AD9762 is available in a 28-lead SOIC package and is specified over the industrial temperature range.
