DAC11001A Overview
Description
The 20-bit DAC11001A, 18-bit DAC91001, and 16-bit DAC81001 (DACx1001) are highly accurate, lownoise, voltage-output, single-channel, digital-toanalog converters (DACs). The DACx1001 are specified monotonic by design, and offer excellent linearity of less than 4 LSB (max) across all ranges.
Key Features
- 1 20-bit monotonic: 1-LSB DNL (max)
- Integral linearity: 4-LSB INL (max)
- Low noise: 7nV/√Hz
- Code independent low glitch: 1 nV-s
- Excellent THD: –105 dB at 1-kHz fOUT
- Fast settling: 1 µs
- Flexible output ranges: VREFPF to VREFNF
- Integrated, precision feedback resistors
- 50-MHz, 4-wire SPI-compatible interface – Readback – Daisy-chain
- Temperature range: –40°C to +125˚C
