DESCRIPTIO  
FEATURES  
The LTC®1657 is a complete single supply, rail-to-rail  
voltageoutput, 16-bitdigital-to-analogconverter(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.  
16-Bit Monotonic Over Temperature  
Deglitched Rail-to-Rail Voltage Output: 8nV•s  
5V Single Supply Operation  
ICC: 650µA Typ  
Maximum DNL Error: ±1LSB  
Settling Time: 20µs to ±1LSB  
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.  
Internal or External Reference  
Internal Power-On Reset to Zero Volts  
Asynchronous CLR Pin  
Output Buffer Configurable for Gain of 1 or 2  
Parallel 16-Bit or 2-Byte Double Buffered Interface  
TheLTC1657issimilartoLinearTechnologyCorporation’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.
