Level shifting D/A converter
This 4-bit D/A converter is implemented by connecting the variable resistors VRH and VRL in series at the ends of
the resistor-string D/A converter resistors. The values of the VRH and VRL variable resistors are modified
according to the value of the low-order 4 bits of the data (D3 to D0) as follows:
— The value of VRH + VRL is held fixed regardless of the value of the data.
— The values of VRH and VRL are changed in R/256 unit steps (where R is the value of the resistor-string D/A
converter unit resistors) over the range zero to 15R/256.
This causes the resistor-string D/A converter V1 and V2 outputs to change in
V/256 steps (where V =
(VH –VL)/256) over the range 0 to 63
× V/256 according to the value of the lower 4 bits of the data.
VrefH/L and REFH/L pins
The VrefH/L pins, which provide a reference voltage to the resistor string, are normally set to VrefH = AVDD and
VrefL = AGND. Note that capacitors (about 10 F) should be connected between REFH and AGND and between
REFL and AGND.
When VrefH is 5.0 V and VrefL is 0 V, the LC78836M outputs its maximum output amplitude as the range 0.5 V
(minimum) to 3.5 V (maximum) (3.0 Vp-p) for 0 dB playback according to the built-in RH and RL resistors.
