LTC2753 Dual Current Output 12-/14-/16-Bit Soft Span DACs with Parallel I/O Features Six Programmable Output Ranges Unipolar: 0V to 5V, 0V to 10V Bipolar: ±5V, ±10V, ±2.5V, - 2.5V to 7.5V - Maximum 16-Bit INL Error: ±1 LSB over Temperature .. - Low 1μA (Maximum) Supply Current - Guaranteed Monotonic over Temperature - Low Glitch Impulse 1n V- s - 2.7V to 5.5V Single Supply Operation - 2μs Settling Time to ±1 LSB - Parallel Interface with Readback of All Registers - Asynchronous CLR Pin Clears DAC Outputs to 0V in Any Output Range - Power-On Reset to 0V - 48-Pin 7mm × 7mm QFN Package - DESCRIPTION The LTC®2753 is a family of dual 12-, 14-, and 16-bit multiplying parallel-input, current-output DACs. These DACs operate from a single 2.7V to 5.5V supply and are all guaranteed monotonic over temperature. The LTC2753A-16 provides 16-bit performance (±1LSB INL and DNL) over temperature without any adjustments. These Soft Span™ DACs offer six output ranges- two unipolar and four bipolar- that can be programmed through the parallel interface, or pinstrapped for operation in a single range. The LTC2753 DACs use a bidirectional input/output parallel interface that allows readback of any on-chip register. A power-on reset circuit resets the DAC outputs to 0V when power is initially applied. A logic low on the CLR pin asynchronously clears the DACs to 0V in any output range. The parts are specified over mercial and industrial temperature ranges. , LT , LTC and LTM are registered trademarks of Linear Technology Corporation.
