Description

The LTC®1657 is a complete single supply, rail-to-rail voltage output, 16-bit digital-to-analog converter (DAC) in a 28-pin SSOP or PDIP package. It includes a rail-to-rail output buffer amplifier, an internal 2.048V reference and a double buffered parallel digital interface.

The LTC1657 operates from a 4.5V to 5.5V supply. It has a separate reference input pin that can be driven by an external reference. The full-scale output can be 1 or 2 times the reference voltage depending on how the X1/X2 pin is connected.

The LTC1657 is similar to Linear Technology Corporation's LTC1450 12-bit VOUT DAC family allowing an upgrade path. It is the only buffered 16-bit parallel DAC in a 28-lead SSOP package and includes an onboard reference for stand alone performance.
