AD825 Transimpedance Amplifier Module Low-Bias-Current JFET Amplifier for Photoelectric Tube Detection

Chip Model: AD825 (Original ADI)

Module Type: Transimpedance Amplifier (TIA)

Features: JFET amplifier, precision current-to-voltage amplifier

Power Supply: ±5V ~ ±15V wide voltage supply

Input Signal Type: Single-ended current input (compatible with direct connection to p otubes)

Input Impedance: High impedance

Input Current Resolution: 10pA (Data from chip datasheet, subject to actual testing)

Input Frequency Range: DC ~ 23MHz (Bandwidth approximately 1.7MHz with a 100KΩ gain resistor, subject to actual measurement)

Output Voltage Range: ±13V (MAX) (@±15V power supply)

Module Gain: Default 100,000 times (adjustable by replacing the gain resistor)

Output Voltage Calculation: Vout = -Iin x Rg (Iin is the input current, Rg is the gain resistor)

Power Protection: Reverse connection protection (no overvoltage protection)

Input/Output Interface: SMA interface + Terminal blocks (3-pin terminal blocks added to the input interface for compatibility with different p otubes)
