The LTC1657/LTC1657L are complete single supply, rail-to-rail voltage output, 16-bit analog-to-digital converters (DAC) in a 28-pin SSOP or PDIP package. They include a rail-to-rail output buffer amplifier, an internal reference and a double buffered parallel digital interface.

The LTC1657/LTC1657L have separate reference input pins that can be driven by an external reference. The fullscale output can be 1 or 2 times the reference voltage depending on how the X1/X2 pin is connected. The LTC1657 operates from a 4.5V to 5.5V supply and has an on-board 2.048V reference. The LTC1657L operates from a 2.7V to 5.5V supply and has an on-board 1.25V reference.

The LTC1657/LTC1657L are similar to the LTC1450/LTC1450L 12-bit VOUT DAC family, allowing an upgrade path. They are the only buffered 16-bit parallel DACs in a 28-lead SSOP package and include an onboard reference for stand alone performance.
