LC2MOS Microprocessor-Compatible 14-Bit DAC AD7538 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, DIP and SOIC Low output leakage <20 nA over the full temperature range Microprocessor-based control systems Digital audio Precision servo control and measurement in high temperature environments FUNCTIONAL BLOCK DIAGRAM VDD 23 AD7538 2 RFB VREF 1 14-BIT DAC 3 IOUT 4 AGND DAC REGISTER 20 LDAC INPUT REGISTER DB13 TO DB0 5 DGND Figure 21 CS 22 WR 24 VSS 01139-001 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 HIGHLIGHTS Guaranteed Monotonicity. The AD7538 is guaranteed monotonic to 14-bits over the full temperature range for all grades. Low Cost. The AD7538, with its 14-bit dynamic range, affords a low cost solution for 12-bit system upgrades. Small Package Size. The AD7538 is packaged in a small 24-pin, DIP and a 24-pin SOIC. Low Output Leakage. By tying VSS Pin 24 to a negative voltage, it is possible to achieve a low output leakage current at high temperatures. Wide Power Supply Tolerance. The device operates on a +12 V to +15 V VDD, with a ±5% tolerance on this nominal figure. All specifications are guaranteed over this range.
