VOLTAGE REFERENCE
A bandgap voltage reference is incorporated on the
ML2330. It is trimmed for zero temperature coefficient at
25°C to minimize output voltage drift over the specified
operating temperature range.
OUTPUT BUFFER AND GAIN SETTING
The output buffer converts the DAC output current to a
voltage output using a resistive network. The outputs can
swing from GND +0.02V to either 2.02V (3V) or 4.02V
(5V). The DAC transfer function is:
V
K
DATA
256
OUT
=
×
+
0 02
.
where K = 2 if V
CC
= 3V and K = 4 if V
CC
= 5V
In the 3V operation, the amplifier outputs will settle to
1/2LSB in 10μs when loads are greater than 1ky (2ky for
5V operation) and capacitive loads smaller than 100pF.
GAIN ERROR
The graph below shows how gain error varies with
temperature when V
CC
= 3.3V.
POWER DOWN MODE
There are three power-down modes in the ML2330. By
clearing the control bits P1-P0 (Table 3.2), the entire chip
will be powered down with a supply current less than
5μA. Individual DACs can also be powered down to save
power (1.75mA per DAC).
