AD7937AR-REEL Overview
The Pbfree Code indicates that the product does not contain any lead, making it environmentally friendly. However, the Part Status is Obsolete, meaning that it is no longer in production. The Terminal Finish is Tin/Lead (Sn85Pb15), which is a common finish for electronic components. The Technology used is CMOS, which stands for Complementary Metal-Oxide-Semiconductor and is known for its low power consumption. This product has 2 functions and a Pin Count of 24. It does not have a Differential Output, meaning that the output signals are not inverted. The Settling Time is 1μs, which is the time it takes for the output to reach a stable state after a change in input. The INL/DNL (LSB) is ±1 (Max), ±1 (Max), indicating the maximum possible error in the output compared to the ideal value. Lastly, the Length of the product is 15.4mm, making it compact and suitable for various applications.

AD7937AR-REEL More Descriptions
DAC 2-CH R-2R 12-bit 24-Pin SOIC W T/R
2 CH DAC, PARALLEL, 8 BITS INPUT
The AD7537 contains two 12-bit current output DAC's on one monolithic chip. A seperate reference input is provided for each DAC. The dual DAC saves valuable board space, and the monolithic construction ensures excellent thermal tracking. Both DAC's are guaranteed 12-bit monotonic over the full temperature range. The AD7537 has a 2-byte (8LSBs, 4MSBs) loading structure. It is designed for right-justified data format. The control signals for registering loading are A0, A1, CS, WR and UPD. Data is loaded to the input registers when CS and WR are low. To transfer this data to the DAC registers, UPD must be taken low with WR. Added features on the AD7537 include an asynchronous CLR line which is very useful in calibration routines. When this is taken low, all registers are cleares. The double buffering of the data inputs allows simultaneous update of both DAC's. Also, each DAC has a seperate AGND line. This increases the device versatility; for instance one DAC may be operated with AGND biased while the other is connected in the standard configuration. The AD7537 is manufactured using the Linear Compatible CMOS (LC²MOS) process. It is speed compatible with most microprocessors and accepts TTL, 74HC an 5V CMOS logic level inputs.
