The OPA396 features a combination of high bandwidth (1 MHz) along with very low quiescent current (23.5 µA) in a high-precision amplifier. These features combined with rail-to-rail input and output make this device an exceptional choice in high-gain, low-power applications. Ultra-low input bias current of 10 fA, 100 µV of offset (maximum), and 1.2 µV/°C of drift over temperature help maintain high precision in ratiometric and amperometric sensor front ends that have demanding low-power requirements. The OPA396 uses Texas Instrument’s proprietary e‑trim™ operational amplifier technology, enabling a unique combination of ultra-low offset and low input offset drift without the need for any input switching or auto-zero techniques. The CMOS-based technology platform also features a modern, robust output stage design that is tolerant of high output capacitance, alleviating stability problems that are common in typical low-power amplifiers.

The OPA3S2859 is a wideband, low-noise programmable gain amplifier with CMOS inputs for wideband transimpedance and voltage amplifier applications. When the device is configured as a transimpedance amplifier (TIA), the 0.9-GHz gain bandwidth product (GBWP) enables high closed-loop bandwidths in low-capacitance photodiode (PD) applications. The three internal switched feedback paths along with an optional parallel non-switched feedback path allows for up to four selectable gain configurations. The internal switches minimize parasitic contributions to increase performance compared to systems that use discrete external switches. Each switch is optimized for feedback resistor values ranging from < 1 kΩ to > 100 kΩ for wide dynamic range applications. The selected switch path is controlled for both channels using a 2-wire parallel interface. For each channel selected, the gain path can also be held constant by exerting the latch pin, which subsequently disables switch control for the selected channel and prevents the channel from changing gain. . . .
