BH2220FVM

D/A Converter Series for Electronic Adjustments Standard 8bit 2ch・3ch Type D/A Converters BH2219FVM, BH2220FVM No.09052EAT01 ●Description The BH2219FVM and BH2220FVM are 8bit R-2R-type D/A converters with 2 and 3 channels, respectively. A compact package allows adjacent placement, thereby eliminating deterioration of the D/A converter due to wire pattern. Furthermore, a built-in RESET function ensures that the output voltage at all channels is Low during power up. A broad power supply voltage range (2.7V-5.5V) is available, providing design flexibility. ●Features 1) Compact package enabling adjacent placement 2) Built-in RESET function 3) High speed output response characteristics 4) 3-line serial interface 5) Broad power supply voltage range: 2.7V-5.5V ●Applications DVCs, DSCs, DVDs, CD-Rs, CD-RWs ●Lineup Parameter Power source voltage range Number of channels Current consumption Differential non linearity error Integral non linearity error Output current performance Settling time Maximum data transfer frequency Input method Data latch method Package ●Absolute Maximum Ratings(Ta=25℃) Parameter Power source voltage Terminal voltage Storage temperature range Power dissipation *1 Derated at 4.7mW/C at Ta>25℃ *2 These products are not robust against radiation BH2219FVM 2.7V to 5.5V 2ch 0.6mA ±1.0LSB ±1.5LSB ±1.0mA 100µs 10MHz CMOS LD method MSOP8 BH2220FVM 2.7V to 5.5V 3ch 0.6mA ±1.0LSB ±1.5LSB ±1.0mA 100µs 10MHz CMOS LD method MSOP8 Symbol VCC VIN TSTG PD Limits -0.3 to 7.0 -0.3 to VCC -55 to 125 470*1 Unit V V ℃ mW Remarks - www.rohm.com © 2009 ROHM Co., Ltd.

(2) Although we are confident in recommending the sample application circuits, carefully check their characteristics further when using them. When modifying externally attached component constants before use, determine them so that they have sufficient margins by taking into account variations in externally attached components and the Rohm LSI, not only for static characteristics but also including transient characteristics. (3) Absolute maximum ratings Operating or testing the device over the maximum specifications may damage the part itself as well as peripheral components. Therefore, please ensure that the specifications are not exceeded. (4) GND potential Ensure that the GND terminal is at the lowest potential under all operating conditions. (5) Thermal design Use a thermal design that allows for a sufficient margin regarding power dissipation (Pd) under actual operating conditions. (6) Terminal shorts and mis-mounting Incorrect orientation or misalignment of the IC when mounting to the PCB may damage part. Short-circuits caused by the introduction of foreign matter between the output terminals or across the output and power supply or GND may also result in destruction. (7) Operation in a strong magnetic field Operation in a strong electromagnetic field may cause malfunction. (8) Reset circuit The power on reset circuit, which initializes internal settings, may malfunction during abrupt power ons. Therefore, set the time constant so as to satisfy the power source rise time. ●Thermal Derating Curve ・MSOP8 500 400 300 200 100 0 0 Board size: 70 x 70 x 1.6mm 25 50 Ta [℃] Material : FR4 glass epoxy board (copper foil area less than 3%) Fig.18 75 100 125 www.rohm.com © 2009 ROHM Co., Ltd.
