AD7641BSTZ

The AD7641BSTZ is a 16-bit, 250 kSPS, successive approximation register (SAR) ADC from Analog Devices. It features high accuracy, low power consumption (5 mW at 250 kSPS), and a ±10V input range. Key specifications include ±1 LSB INL, ±0.5 LSB DNL, and 92 dB SNR.
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.
