[Click the image to enlarge it]

The TLV9004 is a quad-channel low-voltage (1.8 V to 5.5 V) operational amplifier with rail-to-rail input and output swing capabilities. It is targeted to be used in space-constrained applications such as smoke detectors, wearable electronics, and small appliances where low-voltage operation and high capacitive-load drive are required.

Introduction to TLV9004:

The TLV9004 belongs to the TLV900x family of Op-Amps from Texas Instruments. The TLV900x family of low-power, rail-to-rail input and output operational amplifiers is specifically designed for portable applications. The class AB output stage is capable of driving less than or equal to 10‑kΩ loads connected to any point between V+ and V–. The input common-mode voltage range includes both rails and allows the TLV900x devices to be used in any single-supply application.

 

How to Use TLV9004

The circuit shown below is an example of a single-supply photodiode amplifier circuit using the TLV9002. Trans-impedance configuration of an amplifier is typically used to convert the low-level photodiode current to a voltage signal for processing in an MCU. The transfer function between the output voltage (VOUT), the input current, (IIN) and the reference voltage (VREF) is defined in the below equation

 

VOUT =  IN * RF + VREF
