AD7538

LC2MOS向上兼容的14位DAC LC2MOS uP-Compatible 14-Bit DAC

Product Details

The 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.
