Title: Digital/analog converter, display panel drive circuit using the same, and display device
Inventor: MATSUI KIYOHISA
IPC: H03M1/78
Filed: 2003-02-26
Abstract: <P>PROBLEM TO BE SOLVED: To reduce the power consumption of a digital/analog converter where an analogue voltage selected by a digital/analog converter of an R-2R type composed of a data latch circuit 22 and a resistor ladder circuit 23 is outputted via an operational amplifier 24.  <P>SOLUTION: A comparison circuit 26 detects the match/mismatch of data for all bits in digital data. A CMOS tristate output circuit 25 bypasses the data latch circuit 22, the resistor ladder circuit 23, and the operational amplifier 24. If the data of all the bits agree, the operation of the operational amplifier 24 side is interrupted, and the CMOS tristate output circuit 25 is made to operate. Thus, without a special signal, the output circuit is switched in detail for lowering power consumption.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
