OPA846IDR Description

Short technical summary and product information.

The Texas Instruments OPA846IDR is an active, wideband, low-noise, voltage-feedback operational amplifier designed for high-performance applications. It boasts a high gain bandwidth product of 1750MHz and a bandwidth of 500MHz at a gain of Acl. The amplifier offers a high slew rate of 625V/µs and low input voltage noise density of 1.2nV/√Hz.

With very low distortion characteristics, including 2nd harmonic distortion of -76dBc and 3rd harmonic distortion of -109dBc at 5MHz, the OPA846IDR is suitable for demanding signal processing tasks. It operates over an industrial temperature range of -40°C to 85°C and requires a total supply voltage between 10V and 12V. The device is stable for gains greater than or equal to 7.

Available in SOIC (D) 8 and SOT-23 (DBV) 5 packages, the OPA846IDR is designed for applications such as high dynamic range ADC preamps, low-noise wideband transimpedance amplifiers, and low-noise differential receivers. It serves as an upgrade for older parts like the OPA686, CLC425, and LMH6624.

Key specifications include a typical quiescent current per channel of 12.6mA, a maximum offset voltage of 0.6mV at 25°C, and a typical common-mode rejection ratio of 110dB. The input bias current is a maximum of 1.9mA, and the offset voltage drift is typically 1.5µV/°C.
