Description

The LM124, LM224W and LM324x consist of four independent, high gain operational amplifiers with frequency compensation implemented internally. They operate from a single power supply over a wide range of voltages.

Operation from split power supplies is also possible and the low-power supply current drain is independent of the magnitude of the power supply voltage.

Features

• Wide gain bandwidth: 1.3 MHz

• Input common mode voltage range includes ground

• Large voltage gain: 100 dB

• Very low supply current/amplifier: 375 μA

• Low input bias current: 20 nA

• Low input voltage: 3 mV max.

• Low input offset current: 2 nA

• Wide power supply range:
– Single supply: 3 V to 30 V
– Dual supplies: ±1.5 V to ±15 V

Description

The HEF4007UBP is a dual complementary pair and an inverter with access to each device. It has three n-channel and three p-channel enhancement mode MOS transistors.

It has three n-channel and three p-channel enhancement mode MOS transistors. It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input.

Dual Complementary Pair

This includes two complementary MOSFET pairs. These pairs consist of one N-channel MOSFET and one P-channel MOSFET. This dual complementary pair can be used in a variety of applications, including analog switching, digital logic implementation, and signal processing.

Inverter

This IC includes a single inverter. An inverter is a digital circuit element that inverts an input signal. For example, if the input is a logical ‘1’, the output will be a logical ‘0’, and vice versa.

 

Features

• Fully static operation

• 5 V, 10 V, and 15 V parametric ratings

• Standardized symmetrical output characteristics

• Specified from -40 °C to +85 °C

• Complies with JEDEC standard JESD 13-B

• Inputs and outputs are protected against electrostatic effects

This part has an extended mode MOS characteristic characteristic of three n-content and three p-content, and the recommended V_DD power supply range is defined as 3 V to 15 V relative to V_SS (usually called support). Random user inputs should be connected to V_DD, V_SS or other inputs.

Pinouts

1. SP2, SP3: source connections to 2nd and 3rd p-channel transistors

2. DP1, DP2: drain connections from the 1st and 2nd p-channel transistors

3. DN1, DN2 drain connections from the 1st and 2nd n-channel transistors

4. SN2, SN3 source connections to the 2nd and 3rd n-channel transistors

5. DN/P3 common connection to the 3rd p-channel and n-channel transistor drains

6. G1 to G3 gate connections to n-channel and p-channel of the three transistor pairs

 

Applications

· High input impedance amplifiers

· Linear amplifiers

· (Crystal) oscillators

· High-current sink and source drivers

· High impedance buffers.

By integrating the dual complementary pair and inverter into a single chip, design flexibility and space efficiency can be maximized.
