Description
- Product Details
- The AD8426 is a dual-channel, low cost, wide supply range instrumentation amplifier that requires only one external resistor to set any gain from 1 to 1000.
- The AD8426 is designed to work with a variety of signal voltages. A wide input range and rail-to-rail output allow the signal to make full use of the supply rails. Because the input range can also go below the negative supply, small signals near ground can be amplified without requiring dual supplies. The AD8426 operates on supplies ranging from ±1.35 V to ±18 V for dual supplies and 2.2 V to 36 V for a single supply.
- The robust AD8426 inputs are designed to connect to real-world sensors. In addition to its wide operating range, the AD8426 can handle voltages beyond the rails. For example, with a ±5 V supply, the part is guaranteed to withstand ±35 V at the input with no damage. Minimum and maximum input bias currents are specified to facilitate open-wire detection.
- The AD8426 is designed to make PCB routing easy and efficient. The two amplifiers are arranged in a logical way so that typical application circuits have short routes and few vias. Unlike most chip scale packages, the AD8426 does not have an exposed metal pad on the bottom of the part, which frees additional space for routing and vias. The AD8426 offers two in-amps in the equivalent board space of a typical MSOP package.
- The AD8426 is ideal for multichannel, space-constrained industrial applications. Unlike other low cost, low power instrumentation amplifiers, the AD8426 is designed with a minimum gain of 1 and can easily handle ±10 V signals. With its space-saving LFCSP package and 125°C temperature rating, the AD8426 thrives in tightly packed, zero airflow designs.
- The AD8226 is the single channel version of the AD8426.
