Very small QFN package is added to lineup. It is suitable for a small mounting and reduces the mounting area. Description · Guarantee Nonlinearity error : +/-1.0LSB, Differential nonlinearity error : +/-0.7LSB · Data transfer format: 12-bit serial data input type by 3 wire ( DI, SCK, LD ) · Output buffer op-amps: Operable over entire voltage range from almost ground to Vcc ( 0 to 5V ) · High output current capacity: +/-1mA or Higher · Very small size package line-up: QFN-20 (pin pitch: 0.5mm), TSSOP-20 (pin pitch 0.65mm) Number for TSSOP/SOP package Number for QFN package Power on reset 12-bit shift register D/A 8-bit latch 8-bit upper segment R-2R D/A converter 8-bit latch D/A 8-bit latch D/A 8-bit latch D/A 8-bit latch D/A 8-bit latch D/A 8-bit latch 9 3 2 Ao4 Ao3 1 VrefL 4 Ao5 5 Ao6 6 Ao7 7 Ao8 8 VrefU 9 10 Ao9 Ao10 19 20 1 2 3 4 5 6 7 8 Outputs incorporate buffer op-amps that have a drive capacity of 1 mA or above for both sink source, and can operate over the entire voltage range from almost ground to Vcc ( 0 to 5V ), making peripheral elements unnecessary and enabling configuration of a system with few component parts. The R2A20169 is an integrated circuit semiconductor of CMOS structure with 12 channels of built in D/A unnecessary and enabling configuration of a system with few component parts. Channel decoder |
