pA Level Transimpedance Amplifier TIA TLC2201 For Weak Current IV Conversion Preamplifier

pA Level Transimpedance Amplifier TIA TLC2201 For Weak Current IV Conversion Preamplifier

Description:
The main chip TLC2201 of this module is a precision low noise operational amplifier. These devices combine the noise performance of the lowest noise JFET amplifier with the DC accuracy previously only available in bipolar amplifiers. Use silicon gate technology to achieve input offset voltage stability. Its temperature and time far exceed what can be obtained using metal gate technology.  This technology allows the input impedance to reach or exceed the level provided by top-gate JFETs and expensive dielectric isolation devices. The combination of excellent DC and noise performance with a common-film input voltage range including negative rails makes these devices ideal for high-impedance, low-level signal conditioning applications in single-supply or split-supply configurations. The resolution can reach 1pA.

Features:
- Power supply: ±5V
- Input current range: 1pA to 3.3nA (R1 = 1GΩ)
- Output voltage range: ±3.3V
- High-precision main chip with bias current of PA level
- Relationship between output voltage Vout and input current I: Vout = I * R1 (R1 defaults to 1GΩ, input and output are in the same direction)
- The typical cross resistance IV circuit connection method can realize the current measurement with the highest accuracy in principle under the current technical level.
- Module size: 50 x 50 mm
- Positioning hole: M3
- Hole center to edge: 4mm
