Power management IC manufacturer Intersil Corporation recently debuted their new integrated ultra-low noise 24bit ADCs with programmable gain amplifiers. The company's latest product provides optimal measurement accuracy over a wide range of conversion rates with a minimum of external components.

The ISL26102 and ISL26104 are 24bit ADCs that offer an on-chip ultra-low noise programmable gain amplifier (PGA). The ADCs' wide PGA gain range facilitates direct connection to load cells, thermocouples and other popular sensors with a wide variety of sensitivities. The devices feature best-in-class noise performance through their entire output word rate range from 2.5 to 4,000SPS, delivering system flexibility unmatched by competitive devices. The ISL26102 and ISL26104 provide two-channel and four-channel input multiplexers, respectively, and are designed for instrumentation such as weighing systems and temperature monitoring and control. They provide designers of these precision instruments the ability to digitize, with unmatched accuracy, small signals from low cost sensors, without the added cost and complexity of external amplifiers and signal conditioning circuits.

The ISL26102 and ISL26104 are available now in 24-lead TSSOP packages and are priced at $5.45 and $5.95 each, respectively, in 1,000-unit quantities.
