MCP9701T-E/LT

The MCP9701T-E/LT is Microchip’s low‑power, analog temperature sensor. It converts ambient temperature into a linear output voltage.
Key points:
- Output: Vout is proportional to temperature with a fixed slope (0°C ≈ 0.5 V; about 10 mV/°C). This lets you read temperature with a single ADC channel.
- Supply and range: Operates from roughly 2.7–5.5 V and covers typical industrial temps (wide operating range with a -40°C to +125°C usable range in many versions).
- Power: Very low quiescent current (microamps), suitable for battery-powered or energy-sensitive apps.
- Interface: Analog voltage output; simple to integrate with microcontrollers.
- Packaging suffix: -E/LT indicates packaging options such as Tape & Reel and lead-free RoHS compliance (for factory pick-and-place).
- Applications: Environmental monitoring, battery packs, automotive, and general MCU temperature sensing.
Notes: Verify exact voltage range and output at your operating temp in the specific datasheet variant, and ensure your ADC input impedance is compatible with the sensor’s output.

Here are the key features of Microchip MCP9701T-E/LT:
- Integrated linear temperature sensor with voltage output
- 10 mV/°C temperature coefficient
- Supply voltage 2.7–5.5 V; output is ratiometric to Vcc
- Operating temperature range: -40°C to +125°C
- Accuracy: typically around ±2°C (max ~±3°C) over the operating range
- Low quiescent current (~tens of µA)
- No external components required; easy ADC interfacing
- Small, RoHS-compliant packaging (3-pin device; Tape and Reel options)

The MCP9701T-E/LT is supplied in a TO-92-style plastic, 3-lead through-hole package (transistor-style).

- Pin count: 3 pins
- Function: Analog temperature sensor with a voltage output proportional to temperature (VDD, VOUT, GND). VOUT changes linearly with ambient temperature as the device is powered from VDD.
