Detailed Description

ADS850Y is a TI/Burr‑Brown ADS85x family precision analog‑to‑digital converter in a TQFP‑48 package. It uses a SAR (successive‑approximation) conversion core and a fast parallel interface for low‑latency, deterministic data transfer. It is built for accurate, repeatable measurements in industrial, medical, and test equipment. Classified under Integrated Circuits as a Specialized IC.

Key Features

High‑resolution SAR ADC for precision measurement

Parallel data interface for high throughput and simple timing

Sample‑and‑hold for stable conversions

Supports external reference; some family variants include internal reference (see datasheet)

Separate analog and digital supplies for noise isolation

Industrial operating temperature range

Low power per conversion and stable performance over temperature

ESD protection and robust input structure

Proven Burr‑Brown analog performance and long‑term reliability

Key Advantages

Very low latency with parallel readout

Simple control signals work well with MCUs, DSPs, and FPGAs

Deterministic timing simplifies real‑time control

Mature ecosystem and application notes from TI

Multiple grade and family options to fit different environments

Backed by Y‑IC quality control, incoming inspection, and warranty

Packaging

Type: TQFP‑48 (Thin Quad Flat Package)

Case code: TI package code 1066

Material: Molded epoxy, JEDEC compliant, Pb‑free options, RoHS friendly

Leads: 48 gull‑wing pins, typical 0.5 mm pitch, low profile

Size: Compact square body; see datasheet mechanical drawing for exact dimensions

Pin configuration overview: parallel data bus lines, control pins (CS, RD/WR, CONVST, BUSY), analog input pins, reference pins, separate analog/digital supplies and grounds

Thermal characteristics: typical board‑level θJA in the tens of °C/W; improve with solid ground planes, copper area, and airflow

Electrical properties: CMOS/TTL‑compatible digital I/O levels (check VIH/VIL in datasheet); decouple AVDD/DVDD; keep analog input and reference routing short and clean

Handling: Follow MSL guidelines in the datasheet; store and bake per JEDEC as needed

Lifecycle

Status: ADS850Y is a mature TI/Burr‑Brown family device. Lifecycle and stock status can vary by batch and region. Contact Y‑IC for the latest status before design‑in.

Nearing discontinuation: If this exact variant is moving to NRND or EOL, we will notify you and support migration planning.
