Product details

Overview

ADC088S052CIMTX/NOPB from Texas Instruments is an 8-channel, 8-bit successive-approximation ADC with 200–500 ksps throughput, independent analog (2.7–5.25 V) and digital (2.7–V_A) supplies, and SPI/QSPI/MICROWIRE-compatible serial interface. It operates from −40°C to +105°C and delivers ±0.2 LSB INL/DNL, 49.2 dB SINAD, and 7.88-bit ENOB at 40.2 kHz for sensor data acquisition in portable instrumentation.

For engineers reviewing the ADC088S052CIMTX/NOPB datasheet, ADC088S052CIMTX/NOPB pinout, ADC088S052CIMTX/NOPB application, or ADC088S052CIMTX/NOPB equivalent, key selection considerations include channel count, SPI timing compliance (3.2–8 MHz SCLK), low-power shutdown (0.03 µW @ 3 V), TSSOP-16 package thermal resistance (96°C/W), and straight-binary output coding.

Technical Context

The ADC088S052CIMTX/NOPB uses a charge-redistribution DAC architecture with internal track-and-hold, acquiring input voltage over 3 SCLK cycles before executing 13-cycle conversion and serial readout. Its multiplexer supports dynamic channel selection via 3-bit address (ADD2–ADD0) loaded on DIN during each frame.

It features separate AGND/DGND pins, dual-supply operation enabling analog reference sharing (V_A = V_REF), and high-impedance DOUT when CS is high. Timing is fully synchronous to SCLK falling edges, with fixed 16-cycle frame structure: 4 leading zeros, 8-bit result (MSB first), and 4 trailing zeros.

Key Specifications

Parameter	Value and Actual Design Meaning
Resolution	8-bit with no missing codes - guarantees monotonicity and full code coverage across all channels.
Sample Rate	200–500 ksps - supports real-time monitoring of fast transients in automotive and medical sensors.
INL / DNL	±0.2 LSB max - ensures accurate multi-channel calibration without per-channel software correction.
Power (Normal)	1.2 mW @ 3 V / 6.5 mW @ 5 V - enables battery-powered operation with minimal thermal load in TSSOP-16.
Power (Shutdown)	0.03 µW @ 3 V - allows microcontroller-gated power cycling between measurements to extend system runtime.
SINAD / ENOB	49.2 dB / 7.88 bits @ 40.2 kHz - sufficient for 7-bit effective precision in voice-band and physiological signal digitization.
Supply Range	V_A: 2.7–5.25 V; V_D: 2.7–V_A - permits flexible rail assignment and eliminates need for level shifters in mixed-voltage systems.

Pinout & Package

ADC088S052CIMTX/NOPB is housed in a 16-lead Thin Shrink Small Outline Package (TSSOP) with 0.65 mm pitch, 4.4 mm width, and exposed pad not connected internally. Thermal resistance θ_JA = 96°C/W on 4-layer 2 oz. PCB.

Pin/Terminal	Circuit Role	Design Meaning
CS (Pin 1)	Chip Select	Falling edge initiates conversion sequence; holds DOUT active and enables serial frame framing.
VA (Pin 2)	Analog Supply / Reference	Provides both analog power and internal reference voltage; must be bypassed with 1 µF + 0.1 µF ceramics within 1 cm.
AGND (Pin 3)	Analog Ground	Return path for analog inputs and VA; requires star grounding separation from DGND to minimize noise coupling.
IN0–IN7 (Pins 4–11)	Analog Inputs	Single-ended channels accepting 0–V_A signals; input capacitance 33 pF (track) / 3 pF (hold) affects source impedance requirements.
DGND (Pin 12)	Digital Ground	Return path for V_D, SCLK, DIN, DOUT; isolation resistor recommended between DGND and AGND in layout.
VD (Pin 13)	Digital Supply	Supplies logic core and DOUT driver; range 2.7 V to V_A; bypass with 0.1 µF ceramic near pin.
DIN (Pin 14)	Serial Data Input	Loads 8-bit control register (ADD2–ADD0) on rising SCLK edges; determines next channel to convert.
DOUT (Pin 15)	Serial Data Output	Outputs 8-bit straight-binary result MSB-first on falling SCLK edges; high-impedance when CS = high.
SCLK (Pin 16)	Serial Clock	Drives entire timing sequence (min 3.2 MHz, max 8 MHz); controls acquisition (3 cycles), conversion (13 cycles), and readout.

Key Features

Feature	Design Value
Independent Analog/Digital Supplies	Enables clean analog reference (V_A) while interfacing to noisy digital domains (V_D), reducing supply-induced crosstalk.
SPI/QSPI/MICROWIRE Compatibility	Direct connection to common microcontrollers and DSPs without protocol translation or glue logic.
Variable Power Management	Hardware-controlled shutdown via CS high reduces current to 10 nA level, supporting ultra-low-duty-cycle sensing.
Extended Temperature Range	−40°C to +105°C operation validated per specification - suitable for under-hood automotive and industrial environments.
Channel-to-Channel Isolation	67.3 dB at 20 kHz - minimizes inter-channel leakage in multiplexed sensor arrays without external guard traces.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 8-bit, multi-channel SAR ADC applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ADS7822U	8-bit, 200 ksps, single-ended 4-channel; SPI interface; 2.7–5.25 V supply; ±0.5 LSB INL.	Half the channel count; lacks independent V_A/V_D supplies; higher INL limits precision in calibrated systems.	Select when only four inputs are needed and board space is constrained; verify layout isolation for analog integrity.
MAX11100ETE+	8-bit, 500 ksps, 8-channel; SPI-compatible; 2.7–3.6 V supply only; ±0.3 LSB INL; integrated reference.	Narrower supply range excludes 5 V systems; integrated reference reduces external BOM but limits flexibility.	Prefer for 3.3 V-only designs where reference stability outweighs supply versatility; confirm thermal derating at +105°C.

Compared with ADS7822U and MAX11100ETE+, ADC088S052CIMTX/NOPB uniquely supports full 8-channel operation with independent analog/digital supplies, wider voltage range (up to 5.25 V), and tighter ±0.2 LSB linearity - making it optimal for mixed-rail industrial and automotive applications demanding channel density and precision.

FAQ

What is the maximum clock frequency supported by ADC088S052CIMTX/NOPB?

The ADC088S052CIMTX/NOPB supports a maximum SCLK frequency of 8 MHz, as specified in its AC Electrical Characteristics table. Operation above this limit may cause timing violations, incomplete conversions, or corrupted serial output. The minimum clock frequency is 3.2 MHz for guaranteed performance; using lower frequencies requires validation against timing margins in the datasheet.

Does ADC088S052CIMTX/NOPB require an external reference voltage?

No, ADC088S052CIMTX/NOPB does not require an external reference. It uses the analog supply voltage (V_A) as its internal reference, with V_A ranging from +2.7 V to +5.25 V. This simplifies design by eliminating external reference components, though V_A must be well-bypassed (1 µF + 0.1 µF ceramics) and kept low-noise to maintain ADC088S052CIMTX/NOPB's ±0.2 LSB linearity.

How is channel selection implemented on ADC088S052CIMTX/NOPB?

Channel selection on ADC088S052CIMTX/NOPB is controlled via a 3-bit address (ADD2–ADD0) loaded into the device's control register through the DIN pin during each conversion frame. The address determines which of the eight analog inputs (IN0–IN7) will be sampled in the *next* conversion cycle, as defined in Table 3 of the datasheet. No configuration register write is needed between conversions.

What is the power consumption of ADC088S052CIMTX/NOPB in shutdown mode?

In shutdown mode (CS = high), ADC088S052CIMTX/NOPB consumes 0.03 µW typical at +3 V supply and 0.15 µW typical at +5 V supply. This ultra-low quiescent power enables energy-efficient duty-cycled operation in battery-powered systems, with full functionality restored within one SCLK cycle after CS is pulled low.

Can ADC088S052CIMTX/NOPB operate with different analog and digital supply voltages?

Yes, ADC088S052CIMTX/NOPB supports independent analog (V_A) and digital (V_D) supplies, with V_D ranging from +2.7 V to V_A. This allows V_A to be set at 5.0 V for optimal SNR while V_D runs at 3.3 V to interface with modern microcontrollers - provided proper decoupling and ground separation are maintained per the layout guidelines in the datasheet.
