Visão Geral
Description
It operates on a single 5V supply and supports parallel, serial, or daisy-chain interfaces. The device includes an internal reference (2.5V) and buffer, reducing external components. Its fast throughput and low latency make it suitable for industrial control, data acquisition, and instrumentation.
The BSTZ suffix denotes a LQFP-48 package. The ADC also offers on-chip oversampling for improved noise performance.
Key Features:
- 16-bit resolution, 250 kSPS
- ±10V bipolar input range
- Low power: 5 mW (250 kSPS)
- Internal reference & buffer
- Parallel/serial interface options
Ideal for precision applications requiring high-speed, high-resolution conversion.
Equivalent
- AD7606BSTZ: 16-bit, 200 kSPS, 8-channel.
- AD7980: 16-bit, 1 MSPS, lower power.
- LTC2380-16: 16-bit, 2 MSPS, similar performance.
- ADS8860: 16-bit, 1 MSPS, small package.
Check datasheets for exact specs and pin compatibility.
Pinout
Key Functions:
- Analog Input: Single-ended, ±10V range (VIN+ and VIN- pins).
- Reference Input: External reference (REF) or internal buffer option.
- Digital Interface: Parallel (16-bit data bus) or serial (SPI-compatible).
- Control Pins: CNVST (conversion start), BUSY (status), RANGE (input range select).
- Power Supply: +5V (AVDD, DVDD) and ±15V (for analog front-end).
Pin Count: 48 pins (LQFP).
Concise and functional for quick reference.
Application
- Industrial Automation: Process control, PLCs, and data acquisition systems.
- Medical Equipment: Patient monitoring, imaging, and diagnostic devices.
- Test & Measurement: High-resolution oscilloscopes and spectrum analyzers.
- Energy Management: Power quality analysis and smart grid monitoring.
- Defense & Aerospace: Radar, sonar, and avionics systems.
Its low noise, high speed (up to 2 MSPS), and wide dynamic range make it ideal for demanding precision measurement tasks.
