MAX9611 Maxim, MAX9611 Datasheet - Page 5

• Manufacturer Part Number: MAX9611
• Description: The MAX9611/MAX9612 are high-side current-sense amplifiers with an integrated 12-bit ADC and a gain block that can be configured either as an op amp or comparator, making these devices ideal for a number of industrial and automotive applications
• Manufacturer: Maxim

Note 2: All devices are 100% production tested at T
Note 3: V
Note 4: Guaranteed by design.
Note 5: C
