Texas Instruments 5962-9084501MPA

Overview

5962-9084501MPA from Texas Instruments (TLC548M) is a military-grade 8-bit serial-output analog-to-digital converter with monolithic silicon construction, designed for high-reliability embedded data acquisition in harsh environments. It features 2.048 MHz I/O clock support, ±0.5 LSB total unadjusted error, and operates across -55°C to +125°C ambient temperature - used in avionics sensor interfaces and radiation-tolerant telemetry systems.

For engineers reviewing the 5962-9084501MPA datasheet, 5962-9084501MPA pinout, 5962-9084501MPA application, or 5962-9084501MPA equivalent, key selection criteria include its MIL-PRF-38535 Class Q qualification, GDIP1-T8 (8-pin ceramic DIP) package, serial control interface timing (tCONV ≤ 17 µs), and dual reference voltage support (VREF+ ≥ 2.5 V, VREF− ≤ 2.5 V).

Technical Context

This device implements a successive-approximation ADC architecture with internal system clock division, requiring only one external I/O clock signal for full 8-bit conversion and serial data output. Its serial interface uses CS (chip select), I/O CLOCK, and DATA OUT signals - no parallel bus or external reference IC needed.

It supports differential reference operation (VREF+ − VREF− ≥ 1 V), with analog input range bounded by the reference rails; inputs exceeding VREF+ saturate to 0xFF, while those below VREF− yield 0x00. Conversion is initiated on the eighth I/O clock falling edge after CS assertion, and output data is valid within 10 ns after each subsequent clock fall.

FAQ

What is the maximum I/O clock frequency supported by the 5962-9084501MPA?

The 5962-9084501MPA supports an I/O clock frequency up to 2.048 MHz, as specified in MIL-PRF-38535 device type 01. This enables a minimum conversion time of 17 µs and a maximum sampling rate of approximately 58.6 kSPS. Operation above this frequency violates timing specifications and may result in invalid output codes or metastability in the serial data stream of the 5962-9084501MPA.

Does the 5962-9084501MPA require an external reference voltage source?

No - the 5962-9084501MPA accepts externally applied reference voltages at REF+ and REF− pins but does not require an external reference IC. It operates with user-supplied references meeting VREF+ ≥ 2.5 V, VREF− ≤ 2.5 V, and differential ≥ 1 V. The 5962-9084501MPA internally generates its conversion ladder from these inputs and imposes no additional reference current burden beyond leakage.

What is the operating temperature range for the 5962-9084501MPA?

The 5962-9084501MPA is rated for ambient operating free-air temperature from -55°C to +125°C, fully qualified per MIL-PRF-38535 Class Q requirements. All electrical parameters in Table I - including linearity error, conversion time, and supply current - are guaranteed across this full range. This makes the 5962-9084501MPA suitable for deployment in unheated airborne, space, or ground vehicle electronics compartments.

Can the 5962-9084501MPA be used with a single-ended reference configuration?

Yes - the 5962-9084501MPA supports single-ended operation by tying REF− to GND and applying VREF+ between 2.5 V and VCC + 0.1 V. In this mode, the analog input range becomes 0 V to VREF+, and inputs above VREF+ saturate to 0xFF. This configuration is commonly used with resistive sensors and is explicitly validated in the 5962-9084501MPA's recommended operating conditions.

Is the 5962-9084501MPA pin-compatible with commercial-grade TLC548 devices?

No - while functionally derived from the TLC548M, the 5962-9084501MPA uses a GDIP1-T8 ceramic DIP package with gold-plated leads and hermetic sealing, differing from commercial plastic DIP variants in thermal expansion, moisture resistance, and screening. Pin numbering matches, but mechanical and reliability attributes are not interchangeable; the 5962-9084501MPA must be sourced and qualified as a distinct military specification part.
