ANALOG W DEVICES Low Cost4Y2 Digit , DPMs With LEDDisplays AD2024/AD2027 Features "Second Generation" MOS.LSI Design Large 0.43" (11mm) LED Displays - 4% Digit Resolution 20,000 Counts Full Scale Limited Differential Input Either Line Powered (AD2024) or Logic Powered (AD2027) Industry Standard Case Designs APPLICATIONS OBSOLETE High Resolution/High Accuracy R_out for: Test Equipment Process Control Instrumentation Analytical and Scientific Instruments GENERAL DESCRIPTION The AD2024 and AD2027 are low cost 41,1digit DPMs with large LED displays. Both units offer the same Features and identical performance, but the AD2024 is ac line powered and the AD2027 is +5V dc powered. THE BENEFITS OF SECOND GENERATION DESIGN The AD2024 and AD2027 are designed around.MOS-LSI (Metal Oxide Semiconductor, Large Scale Integration) inte- External power supply outputs at +5V and -25V (-25V only on the AD2027) are made available for powering external circuitry. In addition, control inputs for conversion "Hold", display blanking and decimal point selection are provided. INDUSTRY STANDARD CASE DESIGNS Although both the AD2024 and AD2027 have identical electrical designs, they are packaged in the case sizes that have bee industry standards for ac line powered and +5V dc grated circuits which greatly reduce the number of ponents logic powered DPMs respectively. The AD2024 fits the 3.924" and interconnections required to provide the p'erformance and x 1.682" (99.67 x 42.74mm) panel cutout mon to most Features expected in a high resolution 41,1digit DPM. ac line powered DPMs, and the AD2027 fits the 3.175" x This "Second Generation" design, therefore, offers greatly increased reliability and significantly lower cost at little promise in performance. The large 0.43 inch (11mm) LED displays offer the brightness and readability previously available only with gas discharge displays with the added advantage of 1.810" (80.65 x 45.97mm) panel cutout of the Analog...
