All rights reserved. 11.Dec.2015 Rev.001 www.rohm.com p TSZ22111・14・001 D/A Converter Series for Electronic Adjustment 10bit 8ch/10ch D/A Converters BU2505FV BU2506FV General Description The BU2505FV and BU2506FV ICs are 10bit R-2R type D/A converters with 10ch and 8ch outputs, respectively. Cascade connection is available, ensuring suitability for multi-channel applications. Each channel incorporates a full swing output type buffer amplifier with high speed output response characteristics, resulting in a greatly shortened D/A output settling time. The ICs also have digital input pins compatible with TTL levels, and the maximum value of the data transfer frequency is 10MHz. With the variable output range function, the upper and lower limits of the output voltage can be set separately from the power supply voltage. Features ■ Built-in Multi-channel R-2R Type 10bit D/A Converter (BU2506FV: 8 Channels, BU2505FV: 10 Channels) ■ Built-in Full Swing Output Buffer Amplifier for All Channels ■ RESET Terminal to fix the Output Voltage to the Lower Reference Level for All Channels ■ Digital Inputs Compatible with TTL Levels ■ 3-wire Serial Interface and RESET Signal to send a 14bit Format Word (4bit Address and 10bit Data) ■ REVERSE Terminal to select LSB First or MSB First of 10bit Data ■ Cascade Connection is Available Applications ■ Control of the Various Types of Consumer and Industrial Equipment Key Specifications ■ Operating Supply Voltage Range: 4.5V to 5.5V ■ Number of Channels: BU2505FV: 10ch BU2506FV: 8ch ■ Differential Non Linearity Error: ±1.0LSB(Max) ■ Integral Non Linearity Error: ±3.5LSB(Max) ■ Data Transfer Frequency: 10MHz(Max) Packages W(Typ) x D(Typ) x H(Max) SSOP-B20 6.50mm x 6.40mm x 1.45mm Typical Application Circuit ○ Product structure:Silicon monolithic integrated circuit ○This product has no designed protection against radioactive rays.
