The LTC1099 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 5VP-Pinput 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, 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.ApplicationsResolution: 8 BitsConversion Time:2.5µs (RD Mode)2.5µs (WR-RD Mode)Slew Rate Limit (Internal S/H): 2.5V/µsLow Power: 75mW MaxTotal Unadjusted ErrorLTC1099: ±1LSBLTC1099A: ±1/2LSB
