The EL5127, EL5227, EL5327, and EL5427 are low power, high voltage rail-to-rail input/output buffers designed for use in reference voltage buffering applications in small LCD displays. They are available in quad (EL5127), octal (EL5227), 10-Channel (EL5327), and 12-Channel (EL5427) topologies. All buffers feature a -3dB bandwidth of 2.5MHz and operate from just 133µA per buffer. This family also features a continuous output drive capability of 30mA (sink and source).
The quad channel EL5127 is available in the 10 Ld MSOP package. The 8-Channel EL5227 is available in both the 20 Ld TSSOP and 24 Ld QFN packages, the 10-Channel EL5327 in the 24 Ld TSSOP and 24 Ld QFN packages, and the 12-Channel EL5427 in the 28 Ld TSSOP and 32 Ld QFN packages. All buffers are specified for operation over the full -40°C to +85°C temperature range.
