• Description: Voltage Output PROFRAMMABLE SENSOR CONDITIONER
• Manufacturer: BURR-BROWN [Burr-Brown Corporation]

ELECTRICAL CHARACTERISTICS (continued)
BOLDFACE limits apply over the specified temperature range: T
T A = +25°C, V SA = V SD = +5V (V SA = V SUPPLY ANALOG , V SD = V SUPPLY DIGITAL ; V SA must equal V SD ), GND D = GND A = 0, and V REF = REF IN /REF OUT = +5V,
unless otherwise noted.
