Quad 12-bit DAC in a through-hole DIP
The Maxim MAX526DENG+ packs four 12-bit voltage-output DACs into a single 24-pin PDIP. Each channel uses an R-2R ladder architecture with a buffered output, so you get four independent analog voltages from one chip without external op-amps. The parallel data interface means it updates all four DACs at once — useful for simultaneous control loops or multi-channel calibration setups. Settling time is 3 µs typical, fast enough for most industrial process control and ATE applications.
What the ratings mean for your BOM
12-bit resolution with ±1 LSB max INL and DNL means monotonicity is guaranteed across all four channels — no missing codes, so you can trust the output for precision trimming or closed-loop feedback. The external reference input lets you set the full-scale voltage to match your ADC reference or sensor supply, keeping the analog chain consistent. Supply range of 10.8 V to 16.5 V on the analog rail plus a -5 V rail gives headroom for bipolar output stages. The -40°C to 85°C industrial temperature range covers factory-floor gear, outdoor telecom cabinets, and engine-bay electronics without derating.
Package and rework — through-hole, no hot-air drama
24-pin PDIP with 0.300-inch body width. Through-hole mounting accepts standard soldering iron.
Lifecycle and compliance
RoHS3 compliant (lead-free), so it passes EU and global material restrictions. The industrial temperature range and through-hole package make it a stable choice for long-life industrial designs where surface-mount rework cycles are a concern.
