TI claims smallest, lowest power, dual, 500-MSPS DACs
11/7/2011 10:57 AM EST
Texas Instruments Incorporated has released new dual, 500-MSPS digital-to-analog converters (DACs) starting at less than $10 in 1,000 unit quantities. The company reports that its new 12-bit DAC3162 and 10-bit DAC3152 are the smallest, least-expensive and lowest-power devices in their class. Key applications include wideband transmit systems, such as wireless base stations, software defined radio (SDR), point-to-point microwave, e-band radio and portable test equipment. Key features:
Price and Availability
- At 500 MSPS, the DAC3162 uses 135 mW per channel with 20 mA output current and 67 mW per channel with 2-mA output current.
- 7-mm x 7-mm QFN package cuts board space requirements by 50 percent compared to the next smallest dual, 500-MSPS DAC solution.
- Pin-for-pin compatibility
- Simplified interface eliminates the need for the serial peripheral interface (SPI).
Samples of the DAC3162 and DAC3152 are available today in a 48-pin, 7-mm x 7-mm QFN package. Production quantities are expected in November 2011. 1,000-unit pricing will start at $12.60 for the DAC3162 and $9.15 for the DAC3152.
TI also offers evaluation modules (EVMs) for the DAC3162 and DAC3152, complete with a transceiver chain that includes the CDCP1803 clock buffer and TRF370333 quadrature modulator. These new EVMs are compatible with TI's TSW3100 pattern generator module for rapid evaluation. The DAC3162EVM and DAC3152EVM are available now, priced at $199. An IBIS model is also available.
