Texas Instruments SA5532 Dual Low-Noise Operational Amplifier
Texas Instruments SA5532A Dual Low-Noise Operational Amplifier

The SA5532, and SA5532A devices are high-performance operational amplifiers combining excellent dc and ac characteristics.
They feature very low noise, high output-drive capability, high unity-gain and maximum-output-swing bandwidths, low distortion, high slew rate, input-protection diodes, and output shortcircuit protection. These operational amplifiers are compensated internally for unity-gain operation.
These devices have specified maximum limits for equivalent input noise voltage.

The Signal E-Book SLYT701: A compendium of blog posts on op amp design topics (1Q 2017)
I. Op Amp Voltage-Range Issues: Op amp voltage ranges: input and output, clearing some confusion. Rail-to-rail inputs: what you should know. Swinging close to ground: single-supply operation.
II. Offset Voltage: Offset voltage and open-loop gain: they’re cousins. SPICEing offset voltage: how to check the sensitivity of circuits to offset voltage. Where are the trim pins? Some background on offset-voltage trim pins.
III. Input Bias Current: “I need high input impedance!” Input impedance vs. input bias current. Input bias current of CMOS and JFET amplifiers. Temperature effects on input bias current, plus a random quiz. Input bias current cancellation resistors: do you really need them? Internal input bias current cancellation of bipolar op amps.
IV. Stability and Oscillations: Why op amps oscillate: an intuitive look at two frequent causes. Taming the oscillating op amp. Taming oscillations: the capacitive load problem. SPICEing op amp stability. Input capacitance: common mode? Differential? Huh? Op amps: G = 1 stable and decompensated. The inverting attenuator G = -0.1: is it unstable?
V. Dynamic Behavior: Simulating gain bandwidth: the generic op amp model. Slew rate: the op amp speed limit. Settling time: a look at the character of the settling waveform.
VI. Noise: Resistor noise: reviewing basics, plus a fun quiz. Op amp noise: the noninverting amplifier. Op amp noise: but what about the feedback resistors? 1/f noise: the flickering candle. Chopper op amps: are they really noisy?
VII. Other Op Amp Issues: Bypass capacitors: yes, they are needed, but why?. The unused op amp: what to do? Protecting inputs from EOS over-voltage. Differential input clamps: can they affect your op amp circuits? Op amps used as comparators: is it okay?
