Details
The ADS7946SRTET are 14-bit, 2 MSPS analog-to-digital converters (ADCs), with differential and single-ended inputs, respectively.The devicesoperate at a 2 MSPS sample rate with a standard 16-clock data frame. The devices feature both outstanding dc precision and excellent dynamic performance; the ADS7946 is pin-compatible with the 8/10/12-bit ADS7947/8/9 devices. The devices include a two-channel input multiplexer and a low-power successive approximation register (SAR) ADC with an inherent sample-and-hold (S/H) input stage.The ADS7945/6 support a wide analog supply range that allows the full-scale input range to extend to ±5 V differential or 5 V single-ended.A simple SPI™, with a digital supply that can operate as low as 1.65 V, allows for easy interfacing to a wide variety of digital controllers. Automatic power-down can be enabled when operating at slower speeds to dramatically reduce power consumption.Offered in a tiny 3 mm × 3 mm QFN package, the ADS7945/6 are fully specified over the extended temperature range of –40°C to +125°C and are suitable for a wide variety of data acquisition applications where high performance, low power, and small package size are key.

FAQs
What is ADS7946SRTET?
The ADS7946SRTET is a 16-bit, 4-channel analog-to-digital converter (ADC) designed by Texas Instruments. It is suitable for applications requiring high-resolution data acquisition from multiple sensors or sources, such as industrial automation, data logging, and precision measurement systems.
How Does ADS7946SRTET Work?
The ADS7946SRTET works by converting analog voltage signals from up to four input channels into 16-bit digital data with high accuracy and precision. It features a successive approximation register (SAR) architecture, enabling high-resolution measurements at a fast conversion rate. The ADC also includes integrated reference and input buffers for simplified system design.
How Many Pins does ADS7946SRTET have and What are the Functions of the Pinout Configuration?
The ADS7946SRTET is housed in a 16-pin TSSOP (Thin Shrink Small Outline Package) package. The pinout configuration includes:
- VDD, AGND, DGND: Power supply and ground pins.
- REFP, REFN: Reference voltage input pins.
- IN0, IN1, IN2, IN3: Analog input channels.
- CS, CONVST, BUSY, DOUT: Serial interface control and data output pins.
- SDI: Serial data input pin.
What are the Pros and Cons of ADS7946SRTET?
Pros:
- Four Input Channels: Supports multiplexed input channels for flexible sensor interfacing.
- High Resolution: Provides 16-bit resolution for accurate analog-to-digital conversion.
- Integrated Reference: Features an integrated reference and input buffers for simplified system design.
- Low Power Consumption: Operates with low power, suitable for battery-powered applications.
- Small Footprint: The 16-pin TSSOP package offers space-efficient integration into compact designs.
Cons:
- Speed Limitation: May have slower conversion rates compared to lower-resolution ADCs.
- Complex Control Interface: Requires careful management of the serial interface for data acquisition.
- Noisy Environments: Sensitive to noise in high-noise environments, requiring proper noise mitigation techniques.
