These op amps allow many possible combinations of power consumption and gain bandwidth, enabling you to get the best performance for the appropriate accuracy. Rail-to-rail op amps are the perfect fit for applications where the supply voltage range is low and the full dynamic range is necessary at the output. Featured Videos See All
Rail to Rail Input Op Amps - Circuit Cellar
https://circuitcellar.com/resources/quickbits/rail-to-rail-input-op-amps/
The input bias current (the current flowing in or out of the op amp’s input pins) makes an abrupt polarity reversal as the input voltage approaches the positive rail. This is because the op amp transitions between an PNP based differential pair and an NPN one. The designers have included two separate input stages to cover the rail-to-rail ...
Op Amp - Dual Rail-to-Rail - 2.7-6V power @ 80mA output ...

It can run from voltages as low as 2.7V and up to 6V. It has rail to rail input and output, which is a common problem for beginners who don't know how to bias op amps (cheaper op-amps such as the LM358 can't handle a full range of input voltage!) 6 MHz gain bandwidth & 1.6 V/us slew so you can drive fairly fast signals.

https://www.ti.com/lit/gpn/OPA4342
The OPA342 series rail-to-rail CMOS operational amplifiers are designed for low-cost, low-power, min-iature applications. They are optimized to operate on a single supply as low as 2.5V with an input common-mode voltage range that extends 300mV beyond the supplies. Rail-to-rail input/output and high-speed operation make them ideal for driving ...
FAQ: Amplifiers What do rail-to-rail and single supply mean?
https://www.analogictips.com/amplifiers-rail-to-rail-single-supply-mean/
Rails refer to supply voltage levels. An upper rail on the voltage output of an op amp refers to the highest voltage level that it can reach, which is limited by the supply voltage powering the op amp. “Rail-to-rail” implies that the signal swings all the way to supply voltage levels on both the positive and negative rails. But does it? Not really.
Difference between “Single-Supply” and “Rail-to-Rail ...
https://fabmodules.com/difference-between-single-supply-and-rail-to-rail-opamps/
Rail-to-Rail Opamp “Rail-to-Rail Output” means the output voltage swing can come close to it’s V+ and V- supply voltages, often within 10mV to 100mV of it’s V+ or V- rails. They’re usually great for use in low-voltage “Single Supply” systems, like a 5Volt DC system, because you can maximize the signal you can get out of your opamp.
OPA1692: The perfect Op Amp for low power audio? – Cycfi ...
https://www.cycfi.com/2017/08/opa1692-the-perfect-opamp-for-low-power-audio/
The OPA169x operational amplifiers achieve a new level of performance for low-power amplifiers with a low 4.2-nV/√Hz noise density and distortion of 0.000045% at 1 kHz. These op amps offer rail-to-rail output swing to within 150 mV of the power supplies with a 2-kΩ load, which increases headroom and maximizes dynamic range.

In my opinion rail to rail op amps are not necessarily easier to use. Just starting out: get a +/- 15V supply and use some older PDIP available op amps. These will be less expensive as well. The audio classic is the NE5532 and they are less than $1 in quantities of 10 or more. TL072 often used at audio for an FET input op amp.

A rail-to-rail output op-amp allows the output voltages to go all the way down to V-, and all the way up to V+ (well, within a few millivolts). A rail-to-rail input/output (RRIO) op-amp does both. The TLV2371 is RRIO.
