Rohm BH2220FVM Standard 8bit 2ch-e3ch type d/a converter Datasheet

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

●Notes for use
(1) Numbers and data in entries are representative design values and are not guaranteed values of the items.
(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.
