16-Bit Quad SPI DAC Achieves ±1 LSB INL & DNL
Linear Technology Corporation introduces the LTC2754-16, a quad 16-bit current output digital-to-analog converter (DAC) that achieves ±1 LSB integral nonlinearity (INL)and differential nonlinearity (DNL). All four DACs can be software programmed or pin-strapped for one of six unipolar or bipolar output ranges via a simple 4-wire serial interface. Software programmability eliminates the need for expensive precision resistors, gain stages and manual jumpers. The LTC2754-16’s precision DC specifications and flexible SoftSpan output configurability make it suited for multichannel data acquisition modules and automated test equipment. A pin- and software-compatible 12-bit option is also available, making it easy to transition between different resolutions in the end-product. The LTC2754-16 is capable of outputting six unique software-programmable unipolar and bipolar output ranges up to ± 10V.
