For engineers reviewing the 5962-9676201QLA datasheet, 5962-9676201QLA pinout, 5962-9676201QLA application, or 5962-9676201QLA equivalent, this device supports high-accuracy DC-coupled measurements in radiation-tolerant, high-reliability systems requiring guaranteed performance under extreme thermal and EMI stress.

Technical Context

The 5962-9676201QLA implements a sigma-delta architecture with on-chip digital filtering optimized for 60 Hz, 100 Hz, 250 Hz, 500 Hz, and 1 kHz notch frequencies. Its dual differential analog inputs (AIN1±, AIN2±) support bipolar operation with programmable PGA gain (1–128) and transducer burn-out detection current (3–6 µA).

It features self-clocking and external-clocking serial interface modes, synchronous data transfer via SCLK, &R&F&S (Read/Write Strobe), &T&F&S (Transfer Strobe), and SDATA, with timing referenced to MCLKIN (10 MHz max). The device includes internal reference output (2.475–2.525 V), V_BIAS bias voltage generation, and compensation current outputs (16–24 µA) for RTD or bridge excitation.

FAQ

What is the maximum master clock frequency supported by the 5962-9676201QLA?

The 5962-9676201QLA supports a maximum master clock frequency of 10 MHz, as specified in Table I under "Master clock frequency" with f_CLKIN limits of 10 MHz. Operation above this frequency is not guaranteed and may cause timing violations, increased power consumption, or loss of calibration integrity. The device requires MCLKIN whenever exiting STANDBY mode; absence of clock can induce uncalibrated behavior.

Does the 5962-9676201QLA include an internal voltage reference?

Yes, the 5962-9676201QLA provides an internal reference output (REF OUT) with a nominal value of 2.5 V and a guaranteed range of 2.475 V to 2.525 V at full temperature range. This buffered output is explicitly defined in Table I and is intended for use as a stable reference for external circuitry or sensor excitation, eliminating the need for discrete reference ICs in many designs.

How does the 5962-9676201QLA handle sensor open-circuit detection?

The 5962-9676201QLA implements transducer burn-out detection using a dedicated 3–6 µA constant-current source per analog input pair (AIN1±, AIN2±), as specified in Table I under "Transducer burn-out current". When enabled, this current flows through the sensor; an open circuit causes measurable voltage shift at the input, allowing host firmware to flag fault conditions without external circuitry.

What package type is used for the 5962-9676201QLA?

The 5962-9676201QLA uses a hermetically sealed 24-pin GDIP3-T24 (ceramic dual-in-line package), designated as Outline L per MIL-STD-1835. This package features gold-plated leads and is qualified for high-reliability military and space applications, offering superior moisture resistance and thermal stability compared to plastic alternatives.

Is the 5962-9676201QLA radiation-hardened?

The 'Q' in the part number 5962-9676201QLA denotes Device Class Q, indicating certification and qualification to MIL-PRF-38535 with Radiation Hardness Assurance (RHA) per the drawing's RHA designator rules. While the base drawing permits RHA marking, final RHA level (e.g., 100 krad) must be confirmed per vendor certificate of compliance and purchase order specification.
