EL5611 and EL5811 are low power, high voltage rail-to-rail input-output amplifiers primarily targeted at VCOM applications in TFT-LCD displays. The EL5611 contains six amplifiers, and the EL5811 contains eight amplifiers. Operating on supplies ranging from 5V to 15V, while consuming only 2.5mA per amplifier, the EL5611 and EL5811 have a bandwidth of 60MHz (-3dB). They also provide common mode input ability beyond the supply rails, as well as rail-to-rail output capability. This enables these amplifiers to offer maximum dynamic range at any supply voltage. The EL5611 and EL5811 also feature fast slewing and settling times, as well as a high output drive capability of 65mA (sink and source). In addition to VCOM applications, these features make these amplifiers ideal for high speed filtering and signal conditioning application. Other applications include battery power, portable devices, and anywhere low power consumption is important. The EL5611 is available in 8-pin MSOP and 8-pin HMSOP package.
The EL5611 (six‑channel) and EL5811 (eight‑channel) amplifiers are designed for TFT‑LCD and V‑O‑O‑M applications. They operate from a single 4.5 V to 16.5 V supply (or split 5 V‑15 V) while consuming only 2.5 mA per amplifier. Features include rail‑to‑rail input and output, unity‑gain stability, a 75 V/µs slew rate, and a short‑circuit current limit of 180 mA.
These devices are offered in 8‑pin MSOP/HMSOP (EL5611) and 28‑pin HTSSOP (EL5811) packages and are suitable for battery‑powered, portable, high‑speed filtering, signal‑conditioning, video, audio, and test‑equipment applications. The datasheet provides detailed pinouts, absolute maximum ratings, electrical specifications, and typical performance curves to aid designers in PCB layout and thermal management.
