LTC1099 - High Speed 8-Bit A/D Converter with Built-In Sample-and-Hold

Two modes of operation, READ (RD) mode and WRITE-READ (WR-RD) mode, allows easy interface with processors. All timing is internal and edge sensitive which eliminates the need for external pulse shaping circuits. The Stand-Alone (S/A) 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.

Features Built-In Sample-and-Hold No Missing Codes No User Trims Required All Timing Inputs Edge Sensitive for Easy Processor Interface Fast Conversion Time: 2.5µs Latched Three-State Outputs Single 5V Operation No External Clock Overflow Output Allows Cascading TC Input Allows User Adjustable Conversion Time Typical Application
