The SA59400 is a high-accuracy, low power analog-to-digital converter (ADC) featuring an integrated 12-bit high-speed ADC, a programmable gain amplifier (PGA), an oscillator, and a high-accuracy temperature sensor. The PGA provides input ranges from ±128mV to ±4.096V. Capable of performing conversions at data rates up to 4630 samples per second (SPS), the SA59400 enables high-resolution measurements of both small and large signals.
The SA59400 device integrates an input multiplexer (MUX) that supports the measurement of either two differential inputs or four single-ended inputs. An integrated high-accuracy temperature sensor can be used for system-level temperature monitoring or cold-junction compensation in thermocouple applications.
The SA59400 transfers data via a Serial Peripheral Interface (SPI™) and operates in continuous-conversion or single-shot modes. In single-shot mode, the device automatically powers down after a conversion, significantly reducing current consumption during idle periods.
The device has a wide power supply range from 2.7V to 5.5V. It is specified over the extended operating temperature range (–40°C to +125°C) and is available in an MSOP10 package. These features make it ideal for low-power, space-constrained sensor measurement applications.
