December 24, 2009 -- Intersil Corp. has introduced the ISL28117 and ISL28217, the latest members of its bipolar low-power precision operational amplifier series. These new products feature an ideal combination of low noise and low power coupled with low offset voltage, low bias current drift and minimal offset drift over temperature. The products are ideal for applications that require reduced power consumption, high DC accuracy and AC performance needed to condition a wide range of precision analog signals.
The single ISL28117 and dual ISL28217 are capable of reducing signal-conditioning error when compared with competing solutions. This is achieved through a combination of lower noise, lower offset voltage, lower bias current and higher gain accuracy. These amplifiers enable high gain processing of wide common-mode voltage signals with much better accuracy than competing solutions.
Applications are broad and include medical instruments, precision active filters, power supply control, programmable logic controllers and digital oscilloscopes.
Key technical specifications
- Input offset of ±50µV (max).
- Offset TC of 0.6µV/°C (max).
- ±1nA, max input bias current.
- ±5 picoA/°C max input bias current TC.
- 440-µA current consumption.
- 250-nV peak-to-peak noise.
- 2.25-V to 20-V supply range.
The combination of low noise and low power meet the requirements for signal gain front ends in industrial control applications, while reducing overall power consumption for high signal-count designs. Full-trench isolation process technology prevents latch-up, while high ESD ratings of 4.5kV (human body model) and 500V (machine model) are designed to prevent in-field failures for industrial applications such as data acquisition and process control.
Availability and Pricing
The ISL28117 single amplifiers are available in 8-lead SOIC at $0.95 (B-grade) and $0.78 (C-grade) in 1,000-piece quantities. The ISL28217 dual amplifiers are available now in 8-lead SOIC packages at $1.48 (C-grade) and $1.89 (B-grade) each in 1,000-piece quantities.
