reference voltage inputs
There are two reference inputs used with the TLV1544/TLV1548, REF+ and REF–. These voltage values
establish the upper and lower limits of the analog inputs to produce a full-scale and zero-scale reading
respectively. The values of REF+, REF–, and the analog input should not exceed the positive supply or be lower
than GND consistent with the specified absolute maximum ratings. The digital output is at full scale when the
input signal is equal to or higher than REF+ and is at zero when the input signal is equal to or lower than REF–.
programmable conversion rate
The TLV1544/TLV1548 offers two conversion rates to maximize battery life when high-speed operation is not
necessary. The conversion rate is programmable. Once the conversion rate has been selected, it takes effect
immediately in the same cycle and stays at the same rate until the other rate is chosen. The conversion rate
should be set at power up. Activation and deactivation of the power-down state (digital logic active) has no effect
on the preset conversion rate.
