Maxim MAX1160BCPI, MAX1160ACWI, MAX1160ACPI, MAX1160BCWI Datasheet
_______________General Description
The MAX1160 10-bit, monolithic analog-to-digital converter (ADC) is capable of 20Msps minimum word
rates. An on-board track/hold ensures excellent dynamic performance without the need for external components. A 5pF input capacitance minimizes drive
requirement problems.
Inputs and outputs are TTL compatible. An overrange
output is provided to indicate overflow conditions. Output
data format is straight binary. Power dissipation is low at
only 1W with +5V and -5.2V power-supply voltages. The
MAX1160 also accepts wide ±2V input voltages.
The MAX1160 is available in 28-pin DIP and SO packages in the commercial temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
