BH2223GLU-E2

BH2223FV/GLU Standard IC 8bit 10ch D/A converter BH2223FV/GLU BH2223FV/GLU is an 8bit D/A converter for electronic adjustment. The 10-channel DC output voltage can be independently controlled by three-wire serial interface from micro-controller. The D/A converter can generate without loss by Rail-to-Rail output within the setting voltage. The built-in power on reset circuit keeps the output state Low after the power is on and prevents the unstable output state. zApplications The voltage adjustment for DVC, DSC etc. zExternal dimensions (Unit : mm) 5.0±0.2 9 1 8 6.4±0.3 4.4±0.2 0.3Min. 16 1.15±0.1 0.1 zFeatures 1) 8bit 10-channel D/A converters adopting R-2R system. 2) 3-wire 12-bit serial interface. 3) POWER ON RESET circuit. 4) The full scale output voltage range : 2.7V to 5.5V. 5) SSOPB16/VFLGA28 package. 0.65 0.15±0.1 0.1 0.22±0.1 SSOP-B16 0.275 5.0±0.1 P=0.5X7 0.75±0.1 5.0±0.1 1.0MAX 1PINMARK 7 6 5 4 3 2 1 A B C D E F G H B 8 0.5 P=0.5X7 A 0.275 1PIN MARK 27-φ0.275±0.05 0.05 M S A B 0.75±0.1 S 0.08 S VFLGA28 zAbsolute maximum ratings (Ta=25°C) Parameter Power supply voltage Maximum output voltage Storage temperature Power dissipation(SSOPB16/VFLGA28) Symbol Limits Unit VCC −0.3 to +7.0 V VIN −0.3 to VCC V Tstg −55 to +125 400/300 ∗ °C Pd mW ∗Reduced by 4mW/3mW for each increase in Ta of 1°C over 25°C.
