500-MSPS DACs
13 December 2011
TI offers smallest, lowest power dual, 500-MSPS DACs; reducing the cost of wideband transmit systems.
Texas Instruments (TI) is reducing the bill of materials for wideband transmit systems with new dual, 500-MSPS digital-to-analogue converters (DACs).
The 12-bit DAC3162 and 10-bit DAC3152 are the smallest, least-expensive and lowest-power devices in their class and were designed for wideband transmit systems, such as wireless base stations, software defined radio, point-to-point microwave, e-band radio and portable test equipment.
Key features and benefits include:
• Lowest power consumption by at least 30% extends the battery life of portable devices. At 500 MSPS, the DAC3162 uses only 135 mW per channel with 20 mA output current and 67 mW per channel with 2-mA output current
• Small 7mm x 7mm QFN package cuts board space requirements by 50% compared to the next smallest dual, 500-MSPS DAC solution
• Pin-for-pin compatibility makes it easy to achieve 12-bit or 10-bit resolution and cost flexibility without board or software changes
• Simplified interface eliminates the need for the serial peripheral interface (SPI)
