BH2222FV

BH2222FV Standard ICs 8bit 20ch D/A converter BH2222FV BH2222FV is an 8bit D/A converter for electronic adjustment. The 20-channel output voltage can be independently controlled by three-wire serial interface from micro-controller. The built-in power on reset circuit keeps the output state Low after the power is on. 4-channel have data register function. Two kinds of set voltage can be retained, and output voltage can be switched by SEL pin. zApplications The voltage adjustment for DVC, DSC etc. zExternal dimensions (Unit : mm) 10.0±0.2 28 15 7.6±0.3 5.6±0.2 zFeatures 1) 8bit 20-channel D/A converters adopting R-2R system. 2) 3-wire + 1-wire 16-bit serial interface. 3) POWER ON RESET circuit. 4) The full scale output voltage range : 2.7 ~ 5.5V. 5) It is possible to set the two output full scale level independently. 6) 4-channel date Register extension function. 7) SSOP-B28 package. 1 14 1.15±0.1 0.1 0.15±0.1 0.1 0.65 0.22±0.1 SSOP-B28 zAbsolute maximum ratings (Ta=25°C) Parameter Power supply voltage Maximum output voltage Storage temperature Power dissipation Symbol VCC VIN Tstg Pd Limits −0.3~+7.0 −0.3~VCC −55~+125 640 ∗ Unit V V °C mW ∗Reduced by 6.4mW for each increase in Ta of 1°C over 25°C.
