14-Bit High Bandwidth Multiplying DACs with Serial Interface
Features and Benefits
- All grades 14-bit monotonic over the full temperature range
- Low cost, 14-bit upgrade for 12-bit systems
- 14-bit parallel load with double buffered inputs
- Small 24-pin, 0.30” DIP and SOIC
- Low output leakage (<20 nA) over the full temperature range
The AD7538 is a 14-bit monolithic CMOS digital-to-analog converter (DAC) that uses laser trimmed thin-film resistors to achieve excellent linearity.
The DAC is loaded by a single 14-bit wide word using standard chip select and memory write logic. Double buffering, which is optional using LDAC, allows simultaneous updates in a system containing multiple AD7538s.
A novel low leakage configuration enables the AD7538 to exhibit excellent output leakage current characteristics over the specified temperature range.
The AD7538 is manufactured using the linear-compatible CMOS (LC2MOS) process. It is speed compatible with most microprocessors and accepts TTL or CMOS logic level inputs.
Product Lifecycle Not Recommended for New Designs
This designates products ADI does not recommend broadly for new designs.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
