description

The a 12-bit resolution digital-to-analog converter (DAC) specifically optimized for digital data transmission in wired and wireless communication systems. The 12-bit DAC is a member of the CommsDAC series of high-speed, low-power CMOS digital-to-analog converters. The CommsDAC family consists of pin compatible 12-, 10-, and 8-bit DACs. All devices offer identical interface options, small outline package, and pinout. The THS5661 offers superior ac and dc performance while supporting update rates to 100 MSPS. The THS5661 operates from an analog supply 5.5 V. Its inherent low power dissipation 175 mW ensures that the device is well-suited for portable and low-power applications. Lowering the full-scale current output reduces the power dissipation without significantly degrading performance. The device features a SLEEP mode, which reduces the standby power to approximately 25 mW, thereby optimizing the power consumption for system needs. The THS5661 is manufactured in Texas Instruments advanced high-speed mixed-signal CMOS process. A current-source-array architecture combined with simultaneous switching shows excellent dynamic performance. On-chip edge-triggered input latches and 1.2 V temperature-compensated bandgap reference provide a complete monolithic DAC solution. The digital supply range 5.5 V supports 3 V and 5 V CMOS logic families. Minimum data input setup and hold times allow for easy interfacing with external logic. The THS5661 supports both a straight binary and twos complement input word format, enabling flexible interfacing with digital signal processors. The THS5661 provides a nominal full-scale differential output current 20 mA and >300 k output impedance, supporting both single-ended and differential applications. The output current can be directly fed to the load (e.g., external resistor load or transformer), with no additional external output buffer required. An accurate on-chip reference and control amplifier allows the user to adjust this output current from 20 mA down to 2 mA, with no significant degradation of performance. This reduces power consumption and provides 20 dB gain range control capabilities. Alternatively, an external reference voltage and control amplifier may be applied in applications using a multiplying DAC. The output voltage compliance range 1.25 V.

I/O DESCRIPTION Analog ground return for the internal analog circuitry Positive analog supply voltage 5.5 V) Full-scale output current bias External clock input. Input data latched on rising edge of the clock. Compensation and decoupling node, requires 0.1 F capacitor to AVDD. Internal bias node, requires 0.1 F decoupling capacitor to AGND. Data bits 0 through D11 is most significant data bit (MSB), D0 is least significant data bit (LSB). Digital ground return for the internal digital logic circuitry Positive digital supply voltage 5.5 V) Used as external reference input when internal reference is disabled (i.e., EXTLO = AVDD). Used as internal reference output when EXTLO = AGND, requires 0.1 F decoupling capacitor to AGND when used as reference output. Internal reference ground. Connect to AVDD to disable the internal reference source. DAC current output. Full scale when all input bits are set 1 Complementary DAC current output. Full scale when all input bits are 0 Mode select. Internal pulldown. Mode 0 is selected if this pin is left floating or connected to DGND. See timing diagram. No connection Asynchronous hardware power down input. Active high. Internal pulldown. Requires s to power down but ms to power up.
