The MAX5186/MAX5189 are dual 8-bit simultaneous-update, current-output digital-to-analog converters (DACs) designed for superior performance in communications systems requiring analog signal reconstruction with low distortion and low-power operation.
The MAX5186 and MAX5189 are dual, 8‑bit digital‑to‑analog converters designed for high‑speed signal reconstruction in communications systems. They operate from a single 2.7 V to 3.3 V supply and provide simultaneous‑update current or voltage outputs with low distortion and low power consumption.
Key features include three power modes (normal, low‑power standby, shutdown), a 10 pV‑s glitch specification, integrated 1.2 V bandgap reference, and a compact 28‑pin QSOP package. Typical applications are signal reconstruction, digital signal processing, arbitrary waveform generation, and imaging.
| Supply voltage (AVDD/DVDD) | 2.7 V to 3.3 V |
|---|---|
| Full‑scale output current (IFS) | 0.5 mA to 1.5 mA |
| Shutdown current (max) | 1 µA |
| Standby current | 1.0 mA to 1.5 mA |
| Glitch impulse | 10 pV‑s |
| Spurious‑Free Dynamic Range (SFDR) | 72 dBc |
The devices operate from a single supply voltage of 2.7 V to 3.3 V.
The shutdown mode limits the current to a maximum of 1 µA.
The glitch impulse is specified as 10 pV‑s.
Standby current is typically between 1.0 mA and 1.5 mA.
