MAX1617 ON Semiconductor, MAX1617 Datasheet - Page 4

• Manufacturer Part Number: MAX1617
• Description: SMBus Temperature Sensor with Internal and External Diode Input
• Manufacturer: ON Semiconductor

1. Operating current is an average value (including external diode injection pulse current) integrated over multiple conversion cycles. Transient
2. For true recurring conversion time see Conversion Rate register description.
3. Output current should be minimized for best temperature accuracy. Power dissipation within the MAX1617 will cause self–heating and
