The AD7685BRMZ is a 16-bit, charge redistribution successive approximation analog-to-digital converter (ADC) from Analog Devices. It achieves a throughput of 250 kSPS with no missing codes, making it suitable for high-precision data acquisition. The device operates from a single 2.3 V to 5.5 V supply and features a separate logic supply from 1.8 V to 5 V for flexible interface levels.
Key electrical characteristics include a typical integral nonlinearity (INL) of ±0.6 LSB, a signal-to-noise and distortion ratio (SINAD) of 93.5 dB at 20 kHz, and a total harmonic distortion (THD) of -110 dB at 20 kHz. Power dissipation is very low, at 1.4 µW at 2.5 V and 100 SPS, scaling to 4 mW at 5 V and 100 kSPS. The pseudo-differential analog input range is 0 V to VREF, with VREF up to VDD.
The AD7685BRMZ is housed in a 10-lead MSOP package and is designed for surface mount assembly. It uses a proprietary serial interface compatible with SPI, QSPI, MICROWIRE, and DSP protocols, and supports daisy-chaining multiple ADCs. The device is specified for operation over the industrial temperature range of -40°C to +85°C.
The AD7685BRMZ has a resolution of 16 bits.
The maximum sampling rate is 250 kSPS.
The operating temperature range is -40°C to +85°C.
The AD7685BRMZ is available in a 10-lead MSOP (10-MSOP) package for surface mount mounting.
The supply voltage range is 2.3 V to 5.5 V for the main supply, with a separate logic supply from 1.8 V to 5 V.
Typical power dissipation is 1.4 µW at 2.5 V and 100 SPS, 1.35 mW at 2.5 V and 100 kSPS, and 4 mW at 5 V and 100 kSPS.
The AD7685BRMZ is listed as RoHS3 compliant, though this data is unverified.
