Texas Instruments OPA2626 High-Bandwidth High-Precision Op Amps
Texas Instruments OPA2626 High-Bandwidth High-Precision Operational Amplifiers are 16-bit and 18-bit, high-precision, SAR ADC drivers with low total harmonic distortion (THD) and noise. These precision op amps are fully characterized and specified with a 16-bit settling time of 280ns, enabling a true 16-bit effective number of bits (ENOB). These devices offer a high DC precision of only 100µV offset voltage and a wide gain-bandwidth product of 120MHz. These features and low wideband noise of 2.5nV/√Hz make these devices optimized for driving high-throughput, high-resolution SAR ADCs in applications such as the ADS88xx. The Texas Instruments OPA2626 family is available in 5-pin SOT and 8-pin VSSOP packages and is specified for operation from –40°C to +125°C.
