Analog Devices Inc./Maxim Integrated DS600U+

Overview

DS600U+ from Maxim Integrated is a ±0.5°C accurate analog-output temperature sensor in an exposed-pad 8-pin µSOP package, delivering 6.45mV/°C gain with 509mV offset at 0°C, operating from 2.7V to 5.5V across –40°C to +125°C - used for cold-junction thermocouple compensation and portable medical equipment thermal monitoring.

For engineers reviewing the DS600U+ datasheet, DS600U+ pinout, DS600U+ application, or DS600U+ equivalent, this page provides verified technical context, confirmed pin functions, real-world thermostat configuration guidance, and validated alternative options for high-accuracy analog temperature sensing in space-constrained, low-power systems.

Technical Context

The DS600U+ integrates a factory-calibrated analog temperature transducer with dual open-drain thermostat outputs (TO and TO), user-programmable trip-point via VTH input, and active-high shutdown control (SD). Its output voltage (VOUT) follows VOUT = T(°C) × 6.45 mV/°C + 509 mV, enabling direct centigrade reading without external components.

Thermostat operation requires no on-chip hysteresis; trip point is set solely by externally applied voltage on VTH. Shutdown mode reduces supply current from 140 µA to 2.5 µA and places VOUT in high-impedance state, while maintaining thermal response via exposed thermal pad connected to GND or floating.

Key Specifications

Pinout & Package

DS600U+ is housed in an exposed-pad 8-pin µSOP package (0.65 mm pitch, 3.0 mm × 3.0 mm body, 0.8 mm height). The exposed pad must be connected to GND or left floating - never tied to supply - to optimize thermal conduction and measurement accuracy.

Equivalent & Alternatives

The following parts are listed as comparable options for similar analog-output temperature sensor applications.

Compared with LM75BIMM/NOPB and ADT75ARMZ, the DS600U+ uniquely delivers factory-trimmed analog output with ±0.5°C accuracy, dual open-drain thermostat outputs, and shutdown-controlled high-Z VOUT - making it optimal for analog-centric, low-firmware, or hardware-triggered thermal management where component count and response latency matter.

FAQ

What is the operating temperature range of the DS600U+?

The DS600U+ operates over –40°C to +125°C. Its ±0.5°C accuracy is guaranteed from –20°C to +100°C, and ±0.75°C accuracy applies across the full range. This makes DS600U+ suitable for automotive under-hood, industrial control, and medical environments where wide thermal margins are required.

How does the DS600U+ implement thermostat functionality?

The DS600U+ implements thermostat functionality using two open-drain outputs - TO (active-high) and TO (active-low) - triggered when VOUT crosses the voltage applied to the VTH pin. No internal hysteresis exists, so external hysteresis must be added if needed. DS600U+ does not include a built-in voltage reference; VTH must be driven by an external precision source like the MAX6007A.

What is the purpose of the CTG pin on the DS600U+?

The CTG pin on the DS600U+ is dedicated to cold-junction compensation and must be connected directly to GND. It isolates the reference junction path in thermocouple applications, ensuring stable offset and minimizing errors caused by thermal gradients near the sensor die. Leaving CTG unconnected or tying it to VDD invalidates DS600U+ accuracy specifications.

Can the DS600U+ be used without external components?

Yes - the DS600U+ requires no external components for basic temperature readout: VDD, GND, and CTG connections plus a load on VOUT suffice. For thermostat operation, only an external voltage source on VTH is needed. No trimming resistors, capacitors, or ADC support circuitry is required, reducing BOM cost and layout complexity for DS600U+ integration.

What package type and lead finish does the DS600U+ use?

The DS600U+ uses an exposed-pad 8-pin µSOP package (3.0 mm × 3.0 mm, 0.65 mm pitch), and the "+" suffix denotes lead-free (Pb-free) finish per JEDEC J-STD-020A. The exposed thermal pad must be connected to GND or left floating - never tied to VDD - to ensure proper thermal performance and electrical integrity of DS600U+.
