Overview
The AD7883BR-REEL is a 12-bit, 50 kHz throughput Analog-to-Digital Converter (ADC) fabricated in LC2MOS technology. It operates from a single +3 V to +3.6 V supply, consuming typically 8 mW in normal mode and 1 mW in power-down mode. The device features a 15 μs conversion time and a 5 μs track/hold acquisition period. Key electrical specifications include a minimum Signal-to-Noise Ratio (SNR) of 69 dB, ±2 LSB maximum Integral Nonlinearity (INL), and ±1 LSB maximum Differential Nonlinearity (DNL). It utilizes a serial interface with three-state outputs and supports both unipolar (0 to VREF) and bipolar (±VREF) input ranges.
Feature Summary
- Single-supply operation optimized for battery-powered applications
- Integrated power-save mode for reduced energy consumption
- Versatile analog input range configuration via external connections
Applications
- Battery powered portable systems
- Laptop computers
- Telecommunications signal processing
- Audio and sonar signal processing
Procurement Notes
Verify the specific suffix 'REEL' indicates tape-and-reel packaging upon order confirmation. Confirm that the B-version temperature rating (-40°C to +85°C) meets system requirements. Ensure the SOIC-24 package dimensions align with PCB footprint constraints. Validate that the 3 V to 3.6 V supply range matches the target power architecture.
Selection Notes
Select this component when a 12-bit resolution and 50 kHz sampling rate are sufficient for the application. Consider the AD7883 for designs requiring low power dissipation in standby modes. Evaluate the need for internal reference tying versus external references if voltage levels differ from VDD. Compare against higher-speed ADCs if throughput requirements exceed 50 kSPS.
Part Context
The AD7883 belongs to Analog Devices' family of low-power, high-speed monolithic A/D converters. It is designed using Linear Complementary MOS (LC2MOS) technology, combining precision bipolar circuits with low-power CMOS logic. This process enables high accuracy and fast settling times within a compact form factor suitable for mixed-signal environments.
