Overview

Description

The ADM8828ARTZ is a switched-capacitor voltage inverter from Analog Devices, designed to generate a negative voltage from a positive input (1.5V to 5.5V). It delivers up to 50mA of output current with low ripple and high efficiency (~90%).
Key features:
- Compact SOT-23 package (space-saving).
- No external diodes required (integrated charge pump).
- Fixed -Vin output (inverts input voltage).
- Low quiescent current (120µA typical).
Applications include biasing sensors, op-amps, and LCD displays. Its simplicity and small footprint make it ideal for portable and battery-powered devices.
For stable operation, a 1µF flying capacitor and 1µF output capacitor are recommended.

Equivalent

The ADM8828ARTZ is a charge pump voltage inverter. Equivalent alternatives include:
- MAX882 (Maxim Integrated)
- LTC1044 (Analog Devices)
- TC1044S (Microchip)
- ICL7660 (Intersil/Renesas)
These chips perform similar voltage inversion functions with slight variations in specs like current output or efficiency. Always check datasheets for exact compatibility.

Features

The ADM8828ARTZ is a switched-capacitor voltage inverter from Analog Devices. Key features:
- Input Voltage Range: 1.5V to 5.5V
- Output Voltage: Inverts input voltage (e.g., +5V → -5V)
- High Output Current: Up to 50mA
- Low Quiescent Current: 0.5mA (typical)
- Switching Frequency: 150kHz (typical)
- Small Package: SOT-23-6 (compact footprint)
- No External Diodes Required: Integrated charge pump
- Low Output Impedance: ~12Ω (efficient power delivery)
Ideal for generating negative supplies in portable devices, op-amp circuits, and data converters. Minimal external components needed.

Pinout

The ADM8828ARTZ is a switched-capacitor voltage inverter in a 6-pin SOT-23 package.
Pin Functions:
1. GND (Pin 1): Ground connection.
2. C+ (Pin 2): Positive terminal of the flying capacitor.
3. VOUT (Pin 3): Inverted output voltage (typically -VIN).
4. VIN (Pin 4): Input voltage (1.5V to 5.5V).
5. C- (Pin 5): Negative terminal of the flying capacitor.
6. SHDN (Pin 6): Shutdown control (active low; tie to VIN for normal operation).
Function: Converts a positive input voltage to a negative output voltage with minimal external components. Typical applications include generating negative bias for LCDs, sensors, or op-amps.
