Renesas Electronics Corporation Instrumentation, OP Amps, Buffer Amps ISL28272FAZ-T7

The ISL28272FAZ-T7 is a dual micropower instrumentation amplifier designed for single supply operation within a voltage range of +2.4V to +5.5V. It features rail-to-rail input and output capabilities, allowing the input signal to swing 10% above the positive supply rail and down to 100mV below the negative supply with minimal degradation in common-mode rejection ratio (CMRR). This amplifier is optimized for applications requiring a minimum gain of 100, making it suitable for high-gain signal conditioning tasks. Key specifications include a typical supply current of 120µA for both channels, a maximum input bias current of 30pA, and a CMRR of 100dB. The ISL28272FAZ-T7 also has a 3dB bandwidth of 100kHz and a slew rate of 0.5V/µs. It is RoHS compliant and available in a 16-lead QSOP package. This product is particularly well-suited for battery-powered systems, sensor signal conditioning, and medical devices, but is noted as not recommended for new designs.
