(Refer to Figure 1-2 and Figure 1-3). Parameters Sym Min Typ Max Units Conditions Note 1: The MCP6275’s VCM for op amp B (pins VOUTA/VINB+ and VINB–) is VSS +100 mV. 2: The current at the MCP6275’s VINB– pin is specified by IB only. 3: This specification does not apply to the MCP6275’s VOUTA/VINB+ pin. 4: The MCP6275’s VINB– pin (op amp B) has a common mode input voltage range (VCMR) of VSS + 100 mV to VDD – 100 mV. CMRR is not measured for op amp B of the MCP6275. The MCP6275’s VOUTA/VINB+ pin (op amp B) has a voltage range specified by VOH and VOL. 5: Set by design and characterization. 6: Does not apply to op amp B of the MCP6275. 7: All parts with date codes November 2007 and later have been screened to ensure operation at VDD = 6.0V. However, the other minimum and maximum specifications are measured at 2.0V and 5.5V.
