Overview
The AD7893BN-5 is a 12-bit successive approximation analog-to-digital converter (ADC) housed in an 8-pin mini-DIP package. It operates from a single +5 V supply and features a serial interface with a conversion time of 6 μs. The device accepts an input voltage range of 0 V to +5 V and utilizes straight binary output coding. Key performance specifications include a signal-to-noise ratio of 72 dB, ±1/2 LSB relative accuracy, and typical power dissipation of 25 mW. The operating temperature range spans from -40 °C to +85 °C.
Feature Summary
- Integrates a track/hold amplifier and on-chip clock for simplified system design
- Provides a high-speed two-wire serial interface compatible with standard microcontrollers
- Supports single-supply operation with low power consumption suitable for portable applications
Applications
- Battery-powered measurement systems requiring low power consumption
- Industrial data acquisition channels with unipolar signal inputs
- Portable instrumentation utilizing serial communication buses
Procurement Notes
Verify the specific suffix BN-5 corresponds to the plastic DIP package and the 0 V to +5 V input range configuration. Confirm that the required linearity specification matches the ±1/2 LSB rating associated with the B version. Ensure the application environment remains within the specified commercial temperature limits.
Selection Notes
Select this component when a 12-bit resolution and 0 V to +5 V input range are required in an 8-pin form factor. The B version offers improved linearity compared to the A version. Consider the SOIC variant if surface mount technology is preferred over through-hole packaging.
Part Context
This part belongs to the AD7893 family of fast 12-bit ADCs fabricated using LC2MOS technology. The series includes variants with different input ranges and packages. The BN-5 designation specifically identifies the bipolar-zero-adjusted or unipolar offset-adjusted version with enhanced linearity in a plastic dual-in-line package.
Replacement Considerations
The AD7893AN-5 serves as a lower-cost alternative with ±1 LSB linearity. The AD7893BR-5 provides identical electrical characteristics but utilizes an SOIC package instead of the mini-DIP format.
