Description

AD7889ACBZ-RL Overview
There is a Tape & Reel (TR) package available for this product.It was included in the 12-UFBGA, WLCSP package that was sent out.This is mainly due to the SPI interface on the device, which means that it can perform better in terms of data acquisition as a result of this feature.It is mounted in the Surface Mount axis of the machine.I strongly recommend you to redo the circuit if your meter does not display 1.6V~3.6V for the supply voltage, according to how this unit is designed.This chip should have an average operating temperature of -40°C~85°C.In total, there are 12 terminals with their own functions.This device has the part number AD7889 as its base part number.A total of 12 pins are present on the part.With it, you get a reference voltage for External.For your specialized needs, a 12-pin data acquisition device is available.Data acquisition device with high resolution 12-bits.Parts requiring 10nA supply current to function normally require current from the 10nA supply.I recommend a supply voltage of 2.6V in order for this device to run correctly.As a result of combining 6 channels, this video processing device achieves incredible performance.There is a voltage called 2.6V at the supply.In consideration of high-level analog source acquisition, 2 analog IN channels are implemented.

The AD7879/AD7889 are 12-bit successive approximation analog-to-digital converters (SAR ADCs) with a synchronous serial interface and low on-resistance switches for driving 4-wire resistive touch screens. The AD7879/AD7889 work with a very low power supply—a single 1.6 V to 3.6 V supply—and feature a throughput rate of 105 kSPS. The devices include a shutdown mode that reduces current consumption to less than 6 μA. To reduce the effects of noise from LCDs and other sources, the AD7879/AD7889 contain a preprocessing block. The preprocessing function consists of a median filter and an averaging filter. The combination of these two filters provides a more robust solution, discarding the spurious noise in the signal and keeping only the data of interest. The size of both filters is programmable. Other user-programmable conversion controls include variable acquisition time and first conversion delay; up to 16 averages can be taken per conversion. The AD7879/AD7889 can run in slave mode or standalone (master) mode, using an automatic conversion sequencer and timer. The AD7879/AD7889 have a programmable pin that can operate as an auxiliary input to the ADCs, as a battery monitor, or as a general-purpose input/output (GPIO). In addition, a programmable interrupt output can operate in three modes: as a general-purpose interrupt to signal when new data is available (DAV), as an interrupt to indicate when limits are exceeded (INT), or as a pen-down interrupt when the screen is touched (PENIRQ). The AD7879/AD7889 offer temperature measurement and touch pressure measurement. The AD7879 is available in a 12-ball, 1.6 mm × 2 mm WLCSP and in a 16-lead, 4 mm × 4 mm LFCSP. The AD7889 is available in a backside coated version of the WLCSP. Both devices support an SPI interface (AD7879/AD7889) or an I2C interface (AD7879-1/ AD7889-1).
