AD1674BR

Overview

The AD1674BR is a monolithic 12-bit analog-to-digital converter manufactured by Analog Devices Inc. It features an onboard sample-and-hold amplifier (SHA) and supports sampling rates up to 100 kSPS with a full-power bandwidth of 1 MHz. The device utilizes a SAR architecture and accepts single-ended inputs across calibrated unipolar (0 V to +10 V, 0 V to +20 V) or bipolar (±5 V, ±10 V) ranges. It operates on +5 V logic and ±12 V/±15 V analog supplies, dissipating 385 mW to 575 mW. The AD1674BR provides parallel data output via three-state buffers and includes an internal 10 V reference.

Feature Summary

Integrated SHA supporting full Nyquist bandwidth without wait-states
Industry standard pinout compatible with AD574A and AD674A
Calibrated input ranges: 0–10 V, 0–20 V, ±5 V, ±10 V
Flexible digital interface for 8-bit or 12-bit microprocessor connection

Applications

Signal processing systems requiring AC and DC specifications
Traditional DC measurement applications
Industrial control systems with dedicated input ports

Procurement Notes

Verify the specific suffix 'R' indicates the Plastic SOIC-28 package. Confirm the temperature grade 'B' corresponds to the -40°C to +85°C operating range. Ensure the datasheet revision matches the required specifications for integral nonlinearity and power supply rejection ratios.

Selection Notes

Select the AD1674BR when a 12-bit resolution and 100 kSPS speed are required in a surface-mount format. Choose this model over DIP variants if PCB space constraints necessitate an SOIC package. Verify that the system can accommodate the required ±12 V or ±15 V analog supply rails alongside the +5 V logic supply.

Part Context

The AD1674 series is part of Analog Devices' legacy high-performance ADC lineup, implemented using BiMOS II process technology. The AD1674BR specifically denotes the commercial/industrial grade version housed in a 28-lead plastic Small Outline Integrated Circuit (SOIC). It maintains functional compatibility with industry-standard pinouts established by earlier generations.
