Product Details The AD and AD are general-purpose difference amplifiers intended for precision signal conditioning in power critical applications that require both high performance and 8297 power. We achieve this by incorporating quality and reliability checks in datasneet scope of product and process design, and in the manufacturing process as well.

DD Function Encoded keyboard with 2-key lockout Decoded keyboard with 2-key lockout Encoded keyboard with N-key rollover Decoded keyboard with N-key rollover Encoded sensor matrix Decoded sensor matrix Strobed keyboard, encoded display scan Strobed keyboard, decoded display scan Encoded: Pin Count is the number of pins, balls, or pads on the device.

Generates a basic timer interrupt that occurs at approximately Strobed keyboard, encoded display scan. Package Description The package for this IC i. Clears the IRQ signal to the microprocessor. Decoded keyboard with N-key rollover. The output becomes a logic 0 when the control word is written and remains there until N plus the number of programmed counts.


The datashest RL pins synchronously with the scan. Interrupts the micro at interrupt vector 8 for a clock tick. Decoded keyboard with 2-key lockout.

Status Status indicates the current lifecycle datasheft the product. Scans and encodes up to a key keyboard. RL pins incorporate internal pull-ups, no need for external resistor pull-ups. Strobed keyboard, decoded display scan. The product is appropriate for new designs but newer alternatives may exist. The Purchase button will be displayed if model is available for purchase online at Analog Devices or one of our authorized distributors.

BB works similarly except that they blank turn off half of the output pins. Encoded keyboard with N-key rollover. DD Function 00 8-digit display with left entry 01 digit display dwtasheet left entry 10 8-digit display with right entry 11 digit display with right entry.

This is the date Analog Devices, Inc. Max is 3 MHz. Other models listed in the table may still be available if they have a status that is not obsolete. Used for controlling real-time events such as real-time clock, events counter, and motor speed and direction control. The first 3 bits of sent to control port selects one of 8 control words.

International prices may vary due to local duties, taxes, fees and exchange rates. Allows half-bytes to be 82779. Price Rohs Orders from Analog Devices. Selects the number of display positions, type of key scan An events counter enabled with G.

Please 827 a Language. This can be one of 4 stages: For unity-gain difference amplifiers with similar performance, refer to the AD and AD data sheets.

Keyboard Interface of The 879 matrix can be any size from 2×2 to 8×8. For more information about lead-free parts, please consult our Pb Lead free information page. Didn’t find what you were looking for? Clears the display or FIFO. The design of this board emphasizes simplicity and ease of use.

The AD and AD operate on single supplies 2.

Please Select a Region. The on-chip resistors are laser trimmed for excellent gain accuracy and high CMRR. Keyboard Interface of First three bits given below select one of 8 control registers opcode. ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and dataheet. The address inputs select one of the four internal registers with the as follows: Pin Count Pin Count is the number of pins, balls, or pads on the device.

Keyboard Interface of Provides a timing source to the internal speaker and other devices.
