8-bit multiplying DAC in a 16-SOIC — what it does and where it fits
The Maxim Integrated MX7524LCSE+ is an 8-bit multiplying digital-to-analog converter with an R-2R ladder architecture and a current-unbuffered output. It accepts an external reference voltage and delivers a differential output current proportional to the digital code, settling in 500 ns. The parallel data interface and wide single-supply range (5 V to 15 V for both analog and digital) make it a straightforward fit for control-loop outputs, waveform generation, and programmable gain/attenuation circuits in commercial-temperature (0°C to 70°C) environments.
500 ns settling — what it buys you on the bus
The parallel interface latches all 8 bits in one write cycle — no serial shift-out delay.
INL/DNL ±0.5 LSB — monotonicity guaranteed
With a maximum INL and DNL of ±0.5 LSB, the MX7524LCSE+ is guaranteed monotonic. That means every increase in digital code produces a positive (or zero) change in analog output — no non-monotonic glitches that would trip a control loop. The ±1 LSB DNL max on the other edge is still within 8-bit system noise floor for most applications.
