Datasheet Microchip EMC1074 — Ficha de datos

EMC1073 / EMC1074 Multiple Channel 1°C
Temperature Sensors with
Selectable Address
PRODUCT FEATURES Datasheet General Description Features The EMC1073 and EMC1074 are high accuracy, low
cost, System Management Bus (SMBus) temperature
sensors with pin selectable SMBus addresses. „ —
—
—
— Each device provides ±1° accuracy (max) for external
diode temperatures and ±2°C accuracy (max) for the
internal diode temperature. The EMC1073 monitors
three temperature channels (two external and one
internal). The EMC1074 monitors four temperature
channels (three external and one internal). Internal Temperature Monitor „ 3.3V Supply Voltage
