8-bit R-2R DAC with parallel interface
The MAX5480BEEE+T is an 8-bit digital-to-analog converter built on an R-2R ladder architecture, offering either voltage or current output in an unbuffered configuration. The parallel data interface writes all eight bits in a single bus cycle, which suits systems where a dedicated DAC bus is available and latency matters — no serial clock overhead. Settling time is 250 ns to within ±0.5 LSB, so the output reaches its final value within a quarter-microsecond after the data bus settles. This update rate supports control loops and waveform generation in the low-MHz range without external sample-and-hold stages. Integral non-linearity is ±0.5 LSB maximum, differential non-linearity ±1 LSB maximum — the device is monotonic by design, meaning every increase in digital code produces a non-decreasing analog output. No missing codes across the 256-step transfer curve.
Supply, reference, and output flexibility
The external reference input lets the designer set the full-scale output span independently of the supply, so the same DAC can produce a 0–2.5 V swing from a 2.5 V reference or a 0–5 V swing from the 5 V supply. Differential output is available, which means the DAC can drive a balanced signal pair — useful when the load is remote or the signal path crosses a noisy backplane. The unbuffered output, however, means the load impedance appears directly in the R-2R network's termination; a high-impedance buffer or amplifier stage is expected after the DAC output pin in most applications. Operating temperature range is -40°C to 85°C, covering industrial control cabinets, test equipment, and instrumentation that sees seasonal temperature swings or unheated factory floors.
Package, compliance, and sourcing posture
Packaging options include Tape & Reel for reel-fed pick-and-place and Cut Tape for prototype or low-volume builds. No stock-holding claim — quoted per RFQ.
