Product details
Overview
TLV1572ID from Texas Instruments is a 10-bit successive-approximation ADC with 1.25 MSPS throughput, single 2.7–5.5 V supply operation, auto-powerdown (≤10 µA), and SPI/QSPI- and TMS320 DSP-compatible serial interface in an 8-pin SOIC package. It digitizes analog inputs from 0 to VCC and is used in high-speed embedded data acquisition for automotive sensors and digital servos.
For engineers reviewing the TLV1572ID datasheet, TLV1572ID pinout, TLV1572ID application, or TLV1572ID equivalent, this page delivers verified technical context, real-world timing behavior in DSP/µC modes, confirmed SOIC-8 terminal mapping, and validated alternative options for industrial-grade 10-bit serial ADC selection.
Technical Context
The TLV1572ID implements a SAR architecture with inherent sample-and-hold, supporting two distinct serial interface modes: DSP mode (4-wire: CS/SCLK/DO/FS) and µC mode (3-wire: CS/SCLK/DO, FS tied high). Mode selection is latched at CS falling edge via dual-sampled FS input.
Timing is strictly clock-synchronized: conversion requires 10 SCLK cycles, sampling occurs on first SCLK rising edge after CS low (µC mode) or on FS rising edge (DSP mode), and output data is padded with six leading zeros before 10-bit result. Auto-powerdown activates on the 17th SCLK falling edge (DSP) or 16th falling edge (µC).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - delivers 1024 discrete output codes for precision analog measurement |
| Throughput Rate | 1.25 MSPS at 5 V - enables real-time sampling of signals up to ~600 kHz Nyquist bandwidth |
| INL / DNL | < ±1 LSB - guarantees monotonicity and no missing codes across full temperature range (–40°C to 85°C) |
| Power Consumption | 8 mW at 3 V / 25 mW at 5 V - supports battery-powered or thermally constrained systems |
| Auto-Powerdown Current | ≤10 µA - reduces standby power by >99% vs active mode, critical for intermittent sampling |
| SINAD | 59 dB at fIN = 500 kHz - corresponds to ~9.5 ENOB, suitable for medium-fidelity signal capture |
| Reference Input Range | 2.7 V to VCC - allows flexible scaling from internal or external reference without level-shifting |
Pinout & Package
TLV1572ID is housed in an 8-pin SOIC (D) package per JEDEC MS-012, with gull-wing leads, RoHS-compliant NiPdAu finish, and MSL Level-1 rating (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: CS | Chip Select / Powerdown Enable | Active-low control: pulls device into 3-state and auto-powerdown when high; initiates mode detection on falling edge |
| 2: VREF | Reference Voltage Input | Defines full-scale analog input range (0 to VREF); internally connects VREF– to GND |
| 3: GND | Analog/Digital Ground | Common return for analog input, reference, and digital I/O; must be low-impedance for noise immunity |
| 4: AIN | Analog Input | Single-ended input accepting 0 to VCC range; 15 pF input capacitance requires careful driver impedance matching |
| 5: SCLK | Serial Clock Input | Edge-triggered master clock (10 MHz @ 3 V, 20 MHz @ 5 V); controls sampling timing and data shift-out rate |
| 6: VCC | Power Supply | Single 2.7–5.5 V supply powering analog core, reference buffer, and digital interface; decoupling required |
| 7: FS | Frame Sync Input | Mode-select signal: low = DSP mode (synchronized to FS pulses), high = µC mode (SPI-compatible) |
| 8: DO | Serial Data Output | 3-state CMOS output delivering 16-bit frame (6 zeros + 10-bit result); latched on SCLK rising edges |
Key Features
| Feature | Design Value |
|---|---|
| Glueless Serial Interface | Direct connection to TMS320 DSPs and SPI/QSPI microcontrollers-no level shifters, translators, or glue logic required |
| Dual-Mode Operation | Hardware-mode selection (DSP vs µC) via FS pin eliminates firmware configuration overhead and ensures deterministic startup |
| Inherent Sample-and-Hold | Integrated S/H eliminates need for external circuitry, reducing board area and signal path errors in compact designs |
| Low-Power Auto-Powerdown | Automatic entry into ≤10 µA state between conversions-enables energy-efficient burst-mode acquisition in portable systems |
| Flexible Reference Architecture | VREF accepts 2.7 V to VCC, enabling ratiometric sensing or independent precision reference without external regulators |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 10-bit serial ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS7822U | 8-bit resolution, 1 MSPS, SPI-only interface, no FS pin, 2.7–5.25 V supply | Lacks DSP mode and frame sync; lower resolution limits dynamic range in servo or sensor applications | Select when 8-bit precision suffices and only µC interface is needed; not drop-in due to resolution and pinout mismatch |
| TLV2548IPW | 12-bit resolution, 200 kSPS, 8-channel mux, SPI interface, 2.7–5.5 V, 20-pin TSSOP | Slower throughput but higher resolution and multiplexing; incompatible pinout and package | Choose for multi-channel, higher-accuracy systems where speed is secondary; requires PCB redesign |
Compared with ADS7822U and TLV2548IPW, TLV1572ID uniquely balances 10-bit precision, 1.25 MSPS speed, dual-mode serial compatibility, and SOIC-8 footprint-making it optimal for cost-sensitive, space-constrained DSP-coupled systems requiring guaranteed monotonicity and ultra-low standby current.

FAQ
What is the operating temperature range for TLV1572ID?
The TLV1572ID is rated for –40°C to +85°C ambient operating temperature, as confirmed by TI's official packaging addendum and electrical specifications table. This extended industrial temperature grade distinguishes it from the TLV1572CD (0°C to 70°C) and makes TLV1572ID suitable for under-hood automotive and factory-floor applications where thermal resilience is mandatory.
Does TLV1572ID support true SPI mode with CPOL=0 and CPHA=1?
Yes, TLV1572ID supports SPI mode with clock polarity = 0 (SCLK idles low) and clock phase = 1, as explicitly stated in the "Interfacing to SPI/QSPI Microcontrollers" section of the datasheet. In µC mode, sampling begins on the first rising edge of SCLK after CS goes low, and data is output on rising edges while sampled on falling edges-matching standard SPI Mode 1 timing.
How does auto-powerdown work in TLV1572ID, and what triggers exit from that state?
TLV1572ID enters auto-powerdown automatically after the LSB is shifted out: on the 17th SCLK falling edge in DSP mode or 16th falling edge in µC mode, reducing supply current to ≤10 µA. Exit occurs on the next valid SCLK rising edge (µC mode) or FS rising edge (DSP mode), enabling rapid wake-up for burst sampling without software intervention or external reset signals.
Can TLV1572ID operate with a 3-V supply, and what performance trade-offs apply?
Yes, TLV1572ID operates from 2.7 V to 5.5 V. At 3 V, maximum SCLK frequency drops to 10 MHz, limiting throughput to 625 kSPS (half the 5 V rate), and power dissipation falls to 8 mW. AC specs such as SINAD remain specified down to 3 V, ensuring consistent 10-bit fidelity-making TLV1572ID viable for battery-powered instrumentation where efficiency and resolution must coexist.
Is TLV1572ID pin-compatible with other devices in the TLV157x family?
Yes, all TLV157x variants-including TLV1572CD, TLV1572ID, and TLV1572IDR-share identical 8-pin SOIC (D) package dimensions, pinout, and terminal functions. The only differences are temperature grade (CD = 0°C–70°C, ID = –40°C–85°C) and packaging format (tube vs tape-and-reel); thus TLV1572ID can be substituted for CD versions in upgraded thermal environments without layout changes.
