OPERATION
General Description
The LTC2641/LTC2642 family of 16-/14-/12-bit voltage
output DACs offer full 16-bit performance with less than
±2LSB integral linearity error and less than ±1LSB differen-
tial linearity error, guaranteeing monotonic operation. They
operate from a single supply ranging from 2.7V to 5.5V,
consuming 120μA (typical). An external voltage reference
of 2V to V
DD
determines the DAC’s full-scale output volt-
age. A 3-wire serial interface allows the LTC2641/LTC2642
to fit into a small 8-/10-pin MSOP or DFN 3mm
×
3mm
package.
Digital-to-Analog Architecture
The DAC architecture is a voltage switching mode resis-
tor ladder using precision thin-film resistors and CMOS
switches. The LTC2641/LTC2642 DAC resistor ladders are
composed of a proprietary arrangement of matched DAC
sections. The four MSBs are decoded to drive 15 equally
weighted segments, and the remaining lower bits drive
successively lower weighted sections. Major carry glitch
impulse is very low at 500pVsec, C
L
= 10pF, ten times
lower than previous DACs of this type.
