10-Bit, 20Msps, TTL-Output ADC
_______________General Description
The MAX1160 10-bit, monolithic analog-to-digital con-
verter (ADC) is capable of 20Msps 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 voltages. The
MAX1160 also accepts wide ±2V input voltages.
The MAX1160 is available in 28-pin DIP and SO pack-
ages in the commercial temperature range.

______________Detailed Description
The MAX1160 requires few external components to
achieve the stated operation and performance. Figure
2 shows the typical interface requirements when using
the MAX1160 in normal circuit operation. The following
section provides a description of the pin functions, and
outlines critical performance criteria to consider for
achieving the optimal device performance.
Power Supplies and Grounding
The MAX1160 requires -5.2V and +5V analog supply
voltages. The +5V supply is common to analog VCC
and digital DVCC. A ferrite bead in series with each
supply line reduces the transient noise injected into the
analog VCC. Connect these beads as close to the
device as possible. The connection between the beads
and the MAX1160 should not be shared with any other
device. Bypass each power-supply pin as close to the
device as possible. Use 0.1µF for VEE and VCC, and
0.01µF for DVCC (chip capacitors are recommended).
