can be synthesized.
2. This parameter is not tested in production. It is guaranteed by design and device characterization.
3. VITR transconductance depends on the resistor from ITR to VITR. This gain assumes an ideal 4750

the recommended value. Positive cur-
rent is defined as the differential current flowing from PT to PR.
