LTC1099

High Speed 8-Bit A/D

Converter with Built-In

Sample-and-Hold

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.
