A/D Conversion for 3V Systems
The LTC1096/LTC1098 are ideal for 3V systems. Figure 17
shows a 3V to 6V battery current monitor that draws only
70
μ
A from the battery it monitors. The battery current is
sensed with the 0.02
resistor and amplified by the
LT1178. The LTC1096 digitizes the amplifier output and
sends it to the microprocessor in serial format. The
LT1004 provides the full-scale reference for the ADC. The
other half of the LTC1178 is used to provide low battery
detection. The circuit’s 70
μ
A supply current is dominated
by the op amps and the reference. The circuit can be
located near the battery and data transmitted serially to
the microprocessor.
