DESCRIPTION
The LTC
®
2656 is a family of octal 16-/12-bit rail-to-rail
DACs with a precision integrated reference. The DACs have
built-in high performance, rail-to-rail, output buffers and
are guaranteed monotonic. The LTC2656-L has a full-scale
output of 2.5V with the integrated 10ppm/°C reference and
operates from a single 2.7V to 5.5V supply. The LTC2656-H
has a full-scale output of 4.096V with the integrated refer-
ence and operates from a 4.5V to 5.5V supply. Each DAC can
also operate with an external reference, which sets the DAC
full-scale output to two times the external reference voltage.
These DACs communicate via a SPI/MICROWIRE™ com-
patible 4-wire serial interface which operates at clock rates
up to 50MHz. The LTC2656 incorporates a power-on reset
circuit that is controlled by the PORSEL pin. If PORSEL
is tied to GND the DACs reset to zero-scale. If PORSEL is
tied to V
CC
, the DACs reset to mid-scale.

Why is the square wave voltage generated by the inverter circuit measured using the AC voltage range of a digital multimeter much smaller than the theoretical value?
Using the AC voltage range of a digital multimeter to measure the square wave voltage generated by the inverter circuit shows only 0.3V, but it should actually be around 10V. My instructor gave me a w...
