What are the key features of OPA846IDG4?
- Wideband voltage-feedback architecture with 110 dB typical common-mode rejection ratio (CMRR) and 90 dB minimum CMRR for high-fidelity differential signal amplification
- Low input offset voltage of 700 µV maximum and 21 µA maximum bias current enabling precision DC-coupled signal chain designs with minimal offset error
- 8-pin SOIC (R-PDSO-G8) package with integrated frequency compensation reducing external component count and simplifying high-speed PCB layout
What is OPA846IDG4 used for?
The OPA846IDG4 is used in high-speed transimpedance amplifier (TIA) stages for photodiode receivers, video line drivers, and active filter designs where wideband low noise is critical. Its 110 dB CMRR and low offset voltage make it suitable for differential ADC input buffers in data acquisition systems operating at tens of megahertz. Medical imaging front ends, test and measurement instrumentation, and cable driver circuits benefit from the OPA846's combination of voltage-feedback bandwidth and low-noise floor in a compact SOIC-8 footprint.

Frequently Asked Questions
What is the common-mode rejection ratio of the OPA846IDG4, and why does it matter for differential signal applications?
The OPA846IDG4 achieves a typical CMRR of 110 dB and a minimum of 90 dB, which means common-mode noise on the inputs is attenuated by at least 31,623 times relative to the differential signal. This performance level is essential in differential ADC input buffers, medical front ends, and instrumentation amplifiers where common-mode interference from power supply or ground noise must be suppressed.
How does OPA846IDG4 compare to a standard general-purpose op-amp for high-frequency photodiode amplification?
The OPA846IDG4 is a wideband, low-noise voltage-feedback amplifier with a 700 µV maximum offset and 21 µA bias current, delivering GHz-range bandwidth suitable for photodiode transimpedance stages. A general-purpose op-amp typically provides only a few MHz of gain-bandwidth product, causing signal compression at the frequencies encountered in optical receivers or laser pulse detection circuits.
What input offset voltage and bias current specs does OPA846IDG4 specify, and which designs benefit most?
The OPA846IDG4 specifies a maximum input offset voltage of 700 µV and maximum bias current of 21 µA. DC-coupled signal chains such as ADC input buffers, precision active filters, and wideband instrumentation front ends benefit most, as these low offset figures minimize gain error and output voltage error without external trimming.
What package does the OPA846IDG4 use, and how does internal frequency compensation simplify board design?
The OPA846IDG4 is housed in an 8-pin SOIC (R-PDSO-G8) package with 1.27 mm pitch, a widely available SMT footprint. Its internal frequency compensation eliminates the need for an external compensation capacitor in most gain settings, reducing BOM count and saving PCB area in space-constrained high-speed amplifier designs.
