1 Temperature ranges as follows: J, K versions: 0°C to +70°C; A, B versions: 40°C to +85°C.
2 Guaranteed by design and characterization, not production tested.
3 The AD7846 is functional with power supplies of ±12 V. See the Typical Performance Characteristics section.
4 Sensitivity of gain error, offset error, and bipolar zero error to VDD, VSS variations.
AC PERFORMANCE CHARACTERISTICS
These characteristics are included for design guidance and are not subject to test. VREF+ = +5 V; VDD = +14.25 V to +15.75 V; VSS = 14.25 V
to 15.75 V; VCC = +4.75 V to +5.25 V; RIN connected to 0 V, unless otherwise noted.
