Active 8-bit multiplying DAC in a through-hole DIP
The AD7524JNZ: With a 500 ns settling time and a parallel data interface, this DAC is suited for applications where a fast update rate and simple microprocessor bus connection are required — think trimming, level-setting, or waveform generation in industrial control or instrumentation.
The external reference input means the full-scale output current is set by the reference voltage and the internal R-2R network; this allows ratiometric operation or scaling to match the ADC reference on the same board.
Linearity and output flexibility
Integral non-linearity is specified at ±0.5 LSB max, which for an 8-bit DAC means the transfer function stays within half a least-significant bit of ideal — no missing codes across temperature. The differential output provides complementary current outputs, useful for driving balanced inputs or differential amplifiers without extra inversion. The 16-pin DIP package with 0.300-inch row spacing is a standard through-hole footprint that mates with sockets or solders directly into plated-through holes. No MSL concerns — the ceramic or molded DIP body is moisture-insensitive, so no bake step before assembly.
Sourcing and cross-reference note
The AD7524JNZ is an active Analog Devices part, sourced through authorized and independent distribution channels. The closest peer in the same DIP footprint is the AD7542JNZ, a 12-bit DAC with the same R-2R architecture, parallel interface, and through-hole package. The AD7542JNZ has a 2 µs settling time and ±1 LSB INL — a direct resolution upgrade if the design needs 12 bits without a board layout change.
