Product Overview

The PCA9306 is a dual bidirectional I2C-bus and SMBus voltage-level translator with an enable (EN) input, and is operational from 1.0 V to 3.6 V (Vref(1)) and 1.8 V to 5.5 V (Vbias(ref)(2)).

The PCA9306 allows bidirectional voltage translations between 1.0 V and 5 V without the use of a direction pin. The low ON-state resistance (Ron) of the switch allows connections to be made with minimal propagation delay. When EN is HIGH, the translator switch is on, and the SCL1 and SDA1 I/O are connected to the SCL2 and SDA2 I/O, respectively, allowing bidirectional data flow between ports. When EN is LOW, the translator switch is off, and a high-impedance state exists between ports.

LiR2450 Battery

LiR2450 is a typical label for rechargeable 2450 batteries. Depending on the exact chemistry used, the LiR2450 battery typically features nominal voltages of 3.0, 3.2, 3.6, and 3.7 volts.

CR2450 Battery
Lithium 3.0V CR2450 battery is a non-rechargeable button/coin cell battery commonly used in watches, computer motherboards, medical devices, LED flashlights, toys, remote controls, car remote keys, security systems, wearable electronics, etc.

Differences between LiR2450 vs CR2450 
The main differences between CR2450 and LiR2450 batteries in the voltage, capacity, and of course, rechargeable feature.

Voltage difference - due to the voltage difference of ~0.6-0.7 volts, not all devices powered by the CR2450 battery will operate properly when powered by the LiR2450 battery. Actually, this voltage difference may even damage some more sensitive units.

Thus, unless the Owner's Guide of the device you have lists 3.6-3.7V LiR2450 batteries as supported battery type, do NOT replace CR2450 battery with LiR2450 battery.

Capacity difference - CR2450 battery features a much larger capacity than the LiR2450 battery. But, the LiR2450 battery may be recharged up to 500-1000 times, which is a lot.

Note: When charging LiR2450 batteries, be sure to use battery chargers specifically intended for such batteries.

Also, LiR2450 batteries feature a much larger self-discharge rate than CR2450 batteries, and is usually 10-30% per year, sometimes even more.

LiR2450 vs CR2450 Interchangeability
LiR2450 is a typical label for rechargeable 2450 batteries. Depending on the exact chemistry used, the LiR2450 battery typically features nominal voltages of 3.0, 3.2, 3.6, and 3.7 volts.

3.0V rechargeable LiR2450 batteries can be used as a direct replacement for CR2450 batteries since they feature the same (similar) output voltage that never exceeds 3.0 volts and pose no threat for sensitive electronics.

If you want to know more about LiR2450 vs CR2450, you can read its datasheet.

Product Overview

2N2222A is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin. 2N2222A has a gain value of 110 to 800, this value determines the amplification capacity of the transistor. The maximum amount of current that could flow through the Collector pin is 800mA, hence we cannot connect loads that consume more than 800mA using this transistor. To bias a transistor we have to supply current to base pin, this current (IB) should be limited to 5mA.

Product Overview

The PT2399 is a CMOS echo/delay processor developed by Princeton Technology Corp. This digital chip includes an ADC (Analog to Digital converter), 44Kb of RAM to store the samples and a DAC (Digital to Analog converter). Although this chip was created as a simple solution to add delay/reverb/echo to karaokes and set-up entertainment systems, it became very popular in the guitar pedal community due to its ability to emulate BBD-based delay circuits, good price, through-hole package, 5V power supply and tolerance to modifications.

Advantages of the PT2399

The first advantage of the PT2399 is its simplicity of use. Since it integrates many of the components we need, we can make a delay with only the chip and a few components ! Contrary to the BBD which needs a lot of external circuits.

The clock frequency is also much higher than the one used with a BBD. This results in less problems with aliasing and audible clock noise.

The second advantage of the PT2399 is the cost. Where a BBD costs from 3€ to more than 20€ for the famous MN3005, you can find a PT2399 between 1 and 2€. And since it already includes the clock and op-amps, the cost is even lower compared to a BBD circuit.

Disadvantages of the PT2399

The memory in the PT2399 is very limited, so the more you want long times, the less information the memory will be able to store. The sound quality will therefore be deteriorated over the long delays, causing like the BBD some noise problems.

Another problem is that the digital part cannot be accessed directly. You can’t add external memory to it to improve performance with long times.

Another example, the delay time is only controlled with the current on a pin. This is perfect to control the time with just one potentiometer connected to this pin. But it becomes more complicated if you want to precisely control the time with another external circuit, to add a tap tempo for example. Whereas with the BBD, you can generate the clock with any microcontroller.
