ADS7835E

The ADS7835E is a Texas Instruments 8-channel, 12-bit, multiplexed analog-to-digital converter (ADC). It scans eight analog inputs through an on-chip multiplexer and converts them with a successive-approximation (SAR) ADC, delivering the results over a serial interface.
Key features
- 8 input channels, 12-bit resolution
- Single-supply operation (references set full-scale; input range is within Vref or AVDD as configured)
- SPI-/3‑/4‑wire compatible serial interface (clock, data in, data out, chip select)
- On-chip sample-and-hold and mux control
- Low power, small package; E suffix typically denotes industrial/extended temperature range
How it works (high level)
- Host selects a channel and initiates a conversion via the serial bus
- The ADC multiplexes the chosen input, performs a SAR conversion, and outputs a 12-bit result
- Useful for scanning multiple sensors or channels with one ADC
Applications
- Data acquisition, sensor arrays, portable instrumentation, industrial controls
Notes
- Requires external reference (VREF) and proper input conditioning within the specified common-mode and range.

Here are the key features of ADS7835E (concise):
- 12-bit SAR ADC with 8-channel input multiplexer
- 0–VREF input range per channel (external reference)
- SPI/MICROWIRE-compatible 3-wire serial interface (DIN/DOUT/CLK) with chip select
- Single-supply operation: 2.7 V to 5.5 V
- External reference required (VREF) for full-scale range
- E-grade: extended/industrial temperature variant
- Suitable for multiplexed measurements with fast conversion times and moderate power
- RoHS-compliant
Note: For exact electrical specs (sampling rate, input impedance, leakage, power, timing, pinout), refer to the ADS7835E datasheet.

Typically an 8-pin package: SOIC-8 (SOP). An MSOP-8 version is also available.

- Pin count: 16 pins (TSSOP-16/VSSOP-16, RoHS “E” package variant).
- Function: 12-bit, 8-channel analog-to-digital converter with I2C interface. It multiplexes eight analog inputs (IN0–IN7) into a single SAR ADC; data is read over I2C. Includes address select pins for I2C addressing and requires external reference.

- Manufacturer: Texas Instruments (TI)
- What kind of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits.

ADS7835E is a low‑power, 8‑channel multiplexed ADC with a serial interface. Applications include data acquisition systems, sensor arrays, portable instrumentation, process control, automotive and industrial sensing, medical and consumer electronics, motor‑control monitoring, and laboratory measurement equipment.

- Cross-vendor option: Microchip MCP3208 (8-channel, 12-bit, SPI) if SPI interface is acceptable.
