reference voltage inputs
The TLV1562 has two reference input pins: REFP and REFM. The voltage levels applied to these pins establish
the upper and lower limits of the analog inputs to produce a full-scale and zero-scale reading respectively. The
values of VREFP, VREFM, and the analog input should not exceed the positive supply or be less 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 VREFP and is at zero when the input signal is equal to or lower than VREFM. The
internal resistance from VREFP to VREFM may be as low as 20 k
(
±
10%).
The reference voltages must satisfy the following conditions:
VREFP
≤
AVDD – 1 V,
AGND + 0.9 V < VREFM and
3 V
≥
(VREFP – VREFM)
≥
0.8 V
