Product details

12-bit SAR ADC with a flexible front end

The MAX147BCAP+ is a 12-bit successive-approximation-register (SAR) ADC from Analog Devices, built around a MUX-S/H-ADC architecture that handles either four differential or eight single-ended inputs through a single conversion core. The SPI data interface keeps wiring simple — three or four lines to the host controller, no parallel bus overhead. Sampling at 133k samples per second, it fits applications like multichannel data acquisition, battery monitoring, or sensor front ends where 12-bit resolution is enough and you want to avoid a separate analog multiplexer.

Package and temperature — indoor use, compact footprint

Housed in a 20-pin SSOP (5.30 mm body width), the MAX147BCAP+ is a surface-mount part. The 0°C to 70°C commercial temperature range limits it to indoor environments.

Frequently asked questions

What is the sampling rate of MAX147BCAP+?

The MAX147BCAP+ samples at 133k samples per second (133 kSPS), which sets the maximum input signal bandwidth at roughly 66 kHz (Nyquist limit). For anti-aliasing filter design, plan for a corner frequency well below that.

Is MAX147BCAP+ 5V tolerant?

The digital supply range goes up to 5.25V, so the SPI interface can operate at 5V logic levels. The analog supply also accepts up to 5.25V, making the part compatible with 5V systems on both sides.

What is a good replacement for MAX147BCAP+?

Within the same Analog Devices family, the MAX147BCAP+ is the current active order code. For a pin-compatible alternative, look at the MAX147BCAP+ itself — no direct second-source alternate is listed in the record. If you need a different package or temperature range, check the MAX147 series variants (e.g., MAX147BCAP+ is the commercial-temp SSOP version).

What input types does MAX147BCAP+ support?

The MAX147BCAP+ accepts both differential and single-ended inputs. In differential mode you get four channels; in single-ended mode you get eight channels. The input multiplexer selects the configuration under SPI control.
