Programmable Operational Amplifier The LM4250CN is a programmable operational amplifier (op-amp) manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:
### **Specifications:**
- **Supply Voltage Range:** ±4V to ±18V (dual supply) or 8V to 36V (single supply)
- **Input Offset Voltage:** 2 mV (typical)
- **Input Bias Current:** 50 nA (typical)
- **Input Offset Current:** 5 nA (typical)
- **Gain Bandwidth Product:** 1 MHz (typical)
- **Slew Rate:** 0.5 V/µs (typical)
- **Common Mode Rejection Ratio (CMRR):** 90 dB (typical)
- **Power Supply Rejection Ratio (PSRR):** 96 dB (typical)
- **Operating Temperature Range:** 0°C to +70°C (commercial grade)
- **Package:** 8-pin DIP (Dual In-line Package)
### **Descriptions:**
- The LM4250CN is a versatile, low-power programmable op-amp that allows users to adjust its performance characteristics (such as power consumption and speed) by setting an external bias current.
- It is designed for applications requiring low power consumption while maintaining good performance.
- The device is suitable for battery-operated and portable electronics due to its adjustable power dissipation.
### **Features:**
- **Programmable Power Consumption:** Bias current can be adjusted externally to optimize power usage.
- **Low Power Operation:** Consumes as little as 20 µA of supply current when programmed for minimal power.
- **Wide Supply Voltage Range:** Supports both single and dual supply configurations.
- **High Input Impedance:** Minimizes loading effects on signal sources.
- **Short-Circuit Protection:** Built-in protection against output short circuits.
- **Stable Operation:** Internally compensated for stability in most applications.
