Description

The AD5722 / AD5732/AD5752 are dual, 12-/14-/16-bit, serial input, voltage output, digital-to-analog converters. They operate from single-supply voltages from +4.5 V up to +16.5 V or dual supply voltages from ±4.5 V up to ±16.5 V. Nominal full-scale output range is software-selectable from +5 V, +10 V, +10.8 V, ±5 V, ±10 V, or ±10.8 V. Integrated output amplifiers, reference buffers, and proprietary power-up/power-down control circuitry are also provided. The parts offer guaranteed monotonicity, integral nonlinearity(INL) of ±16 LSB maximum, low noise, and 10 μs typical settling time.

Part Number: DAC5652A

Function: DUAL, 10-BIT 275 MSPS DIGITAL-TO-ANALOG CONVERTER

Package: 48-Pin Thin-Quad Flat Pack (TQFP) Type

Manufacturer: Texas Instruments

Pinouts:

 

Description

The DAC5652 is a monolithic, dual-channel, 10-bit, high-speed DAC with on-chip voltage reference.Operating with update rates of up to 275 MSPS, the DAC5652A offers exceptional dynamic performance, tight gain, and offset matching characteristics that make it suitable in either I/Q baseband or direct IF communication applications.
Each DAC has a high-impedance, differential-current output, suitable for single-ended or differential analog output configurations. External resistors allow scaling of the full-scale output current for each DAC separately or together, typically between 2 mA and 20 mA. An accurate on-chip voltage reference is temperature-compensated and delivers a stable 1.2-V reference voltage. Optionally, an external reference may be used.

The DAC5652A has two, 10-bit, parallel input ports with separate clocks and data latches. For flexibility, the IC also supports multiplexed data for each DAC on one port when operating in the interleaved mode. The device has been specifically designed for a differential transformer-coupled output with a 50-Ω doubly terminated load. For a 20-mA full-scale output current, both a 4:1 impedance ratio (resulting in an output power of 4 dBm) and 1:1 impedance ratio transformer (–2 dBm output power) are supported.

The DAC5652A is available in a 48-pin TQFP package. Pin compatibility between family members provides 10-bit (DAC5652A), 12-bit (DAC5662), and 14-bit (DAC5672) resolution. Furthermore, the DAC5652A is pin compatible to the DAC2900 and AD9763 dual DACs. The device is characterized for operation over the industrial temperature range of –40°C to 85°C.
