LTC2752 Dual16-Bit SoftSpan I DACs OUT Fae Tseru Dpircse Tnoi n Program or Pin-Strap Six Output Ranges The LTC 2752 is a dual 16-bit multiplying serial-input, 0V to 5V, 0V to 10V, 2.5V to 7.5V, 2.5V, 5V, 10V current-output digital-to-analog converter. It operates from n Maximum 16-Bit INL Error: 1 LSB over a single 3V to 5V supply and is guaranteed monotonic Temperature over temperature. The LTC2752A provides full 16-bit n Guaranteed Monotonic over Temperature performance (1LSB INL and DNL, max) over temperature n Glitch Impulse 0.6nVs (3V), 2.2nVs (5V) without any adjustments. This SoftSpan DAC offers n Serial Readback of All On-Chip Registers six output ranges (up to 10V) that can be programmed n 1A Maximum Supply Current through the 3-wire SPI serial interface, or pinstrapped for n 2.7V to 5.5V Single-Supply Operation operation in a single range. n 16-Bit Settling Time: 2s Any on-chip register (including DAC output-range set- n Voltage-Controlled Offset and Gain Trims tings) can be read for verification in just one instruction n Clear and Power-On-Reset to 0V Regardless of cycle and if you change register content, the altered Output Range register will be automatically read back during the next n 48-Pin 7mm 7mm LQFP Package instruction cycle. Voltage-controlled offset and gain adjustments are also a acilpp Tsnoi provided and the power-on reset circuit and CLR pin both n High Resolution Offset and Gain Adjustment reset the DAC outputs to 0V regardless of output range. n Process Control and Industrial Automation L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks and n SoftSpan is a trademark of Linear Technology Corporation.
