10-Bit, 40Msps, TTL-Output ADC
_______________General Description
The MAX1161 10-bit, monolithic analog-to-digital con-
verter (ADC) is capable of 40Msps minimum word
rates. An on-board track/hold ensures excellent dynam-
ic performance without the need for external compo-
nents. 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 volt-
ages. The MAX1161 also accepts wide, ±2V input volt-
ages.
The MAX1161 is available in 28-pin DIP and SO pack-
ages in the commercial temperature range.
