OPA2328 的說明
The single-channel OPA328, dual-channel OPA2328 and quad-channel OPA4328 (OPAx328) are a new generation family of precision, low-voltage CMOS operational amplifiers optimized for very low noise and wide bandwidth.
The OPAx328 have a linear input stage with zero-crossover distortion that delivers excellent common-mode rejection ratio (CMRR) of 120dB (typical) over the full input range. The input common-mode voltage range extends 100mV beyond the negative and positive supply rails. The output voltage typically swings within 10mV of the rails.
The OPAx328 also use 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.
Low-noise (6.1nV/√Hz) and high-speed operation (40MHz, 30V/µs) make these devices a great choice for driving sampling analog-to-digital converters (ADCs).
The OPAx328 are also a great choice for high-impedance-input, single-supply applications. Low input bias current and low input capacitance allows for high-frequency transimpedance gains at low photocurrent operation (< 1nA).
