ADI LTC1099ACN#PBF

The LTC1099 is a high speed microprocessor compatible 8-bit analog-to-digital converter (A/D). An internal sampleand-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 5Vp-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 involving 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.
