Overview
LTC2753 Dual Current Output 12-/14-/16-Bit SoftSpan 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 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 SoftSpan™ 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 commercial and industrial temperature ranges.
