Hello,
I work with pga302 datasheet and have a couple of questions:
Q1. In the datasheet internal voltage reference TC specified as +/- 250 ppm/C.
Is this typo ?
Q2. My project is - design pressure transmitter. The sensor is piezoresistive bridge.
Assume , the sensor is ideal . What could be the best accuracy , that pga302 can achieve ?
On page 68, table 67 the numbers look strange. E.g. VINPP - VINPN = 34.651 mV, VOUT EXPECTED = 0.5 V
VINPP - VINPN = 13.844 mV, VOUT EXPECTED = 2.5 V
----
I assume that gain is the same for all rows. Please, explain.
Thank you in advance,
Ruben
