Overview
The AD1671KP is a monolithic 12-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates at a throughput rate of 1.25 MSPS with an 800 ns conversion time. The device integrates a high-performance sample-and-hold amplifier (SHA) and a voltage reference, consuming 570 mW. It supports pin-configurable input ranges including ±5 V, 0 to +5 V, ±2.5 V, and 0 to +2.5 V. The component utilizes a subranging flash architecture with digital error correction and provides data in two's complement or offset binary formats. It is housed in a 28-pin Plastic Leaded Chip Carrier (PLCC) package.
Feature Summary
- Integrated on-chip sample-and-hold amplifier (SHA) and voltage reference
- Subranging flash conversion architecture with digital error correction
- Pin-strappable input ranges: ±5 V, 0 to +5 V, ±2.5 V, 0 to +2.5 V
- Out-of-range indicator (OTR) for overflow detection
Applications
- High-speed modems
- Digital radios
- Communication systems requiring fast sampling rates
Procurement Notes
Verify the specific suffix 'KP' corresponds to the 28-pin PLCC package and K grade linearity specifications. Confirm availability status as distribution channels may list discontinued variants. Ensure environmental compliance requirements match the manufacturing date code.
Selection Notes
Select the AD1671KP when a 12-bit resolution and 1.25 MSPS speed are required within a single chip solution. The K grade offers improved integral nonlinearity compared to the J grade. Consider the PLCC package for surface mount applications where leaded DIP options are unsuitable.
Part Context
The AD1671 series represents a family of complete monolithic ADCs designed to replace hybrid implementations. The KP variant specifically denotes the plastic surface-mount package option within the 0°C to +70°C temperature range operating class.
Replacement Considerations
Direct replacements include other AD1671 grades such as AD1671JQ or AD1671JP depending on required linearity accuracy and package type preferences.
