Analog Devices Inc. LTC2668 Digital-to-Analog Converters

Analog Devices Inc. LTC2668 Digital-to-Analog Converters are 16-channel, 16-/12-bit ±10V converters with integrated precision references. The LTC2668s from Analog Devices are guaranteed monotonic over temperature and have built-in rail-to-rail output buffers. These SoftSpan™ DACs offer five output ranges up to ±10V. The range of each channel can be programmed independently. The part can be hardware-configured for operation in a fixed range.
