LTC2688
Overview
The LTC2688 is a 16-channel,12-/16-bit, ±15 V digital-to-analog converter (DAC) with an integrated precision reference. The LTC2688 is guaranteed monotonic and has built in rail-to-rail output buffers that can source or sink up to 20 mA.
- 16 independent SoftSpan DAC channels
- Independently programmable output ranges: 0 V to 5 V, 0 V to 10 V, ±5 V, ±10 V, ±15 V
- Full 12-/16-bit resolution at all ranges
- Flexible single- or dual-supply operation
- Maximum INL error: ±3 LSB16, ±0.75 LSB12
- Precision 4.096 V reference, ±5 ppm/°C maximum
- A/B toggle or sinusoidal dither using up to 3 toggle pins
- Multiplexer for output voltage and load current sense
- Outputs drive ±20 mA guaranteed
- 6 mm × 6 mm, 40-lead LFCSP and 4.5 mm × 4.5 mm, 64-ball WLCSP
