High Speed 8-Bit A/D
Converter with Built-In

DESCRIPTIO
The LTC
®
1099 is a high speed microprocessor compatible
8-bit analog-to-digital converter (A/D). An internal sample-
and-hold (S/H) allows the A/D to convert inputs up to the
full Nyquist limit. With a conversion rate of 2.5µs, this
allows 156kHz 5V
P-P
input signals or slew rates as high as
2.5V/µs, to be digitized without the need for an external
S/H.
Two modes of operation, Read (RD) mode and Write-Read
(WR-RD) mode, allow easy interface with processors. All
timing is internal and edge sensitive which eliminates the
need for external pulse shaping circuits. The Stand-Alone
(SA) mode is convenient for those applications not involv-
ing a processor.
Data outputs are latched with three-state control to allow
easy interface to a processor data bus or I/O port. An
overflow output (OFL) is provided to allow cascading for
higher resolution.
