STMicroelectronics TS613ID

Overview

TS613ID from STMicroelectronics is a dual high-output-current operational amplifier designed for ADSL upstream line driving, featuring 200mA min. output current per channel, 130MHz gain-bandwidth product, 40V/µs slew rate, and specified operation into 25Ω loads at ±6V supply. It delivers low intermodulation distortion (–77dBc IM2/IM3) and ultra-low noise (3nV/√Hz, 1.2pA/√Hz), enabling simultaneous multi-carrier amplification in DSL remote terminals.

For engineers reviewing the TS613ID datasheet, TS613ID pinout, TS613ID application, or TS613ID equivalent, key selection criteria include its 25Ω load drive capability, ±4.5V output swing at 160mA, thermal performance in SO8 Exposed-Pad package, and differential line driver implementation with single +12V supply biasing.

Technical Context

The TS613ID integrates two independent wideband op-amps optimized for high-fidelity analog signal transmission under heavy resistive loading. Its architecture supports stable closed-loop gain of +2 to +11 into 25Ω//15pF, with phase margins of 60° (AVCL = 14dB) and 40° (AVCL = 6dB), ensuring robustness in ADSL upstream emission paths.

It operates across –40°C to +85°C with ±2.5V to ±6V supply range, common-mode input voltage from (VCC–) +2V to (VCC+) –1V, and features internal short-circuit protection. The exposed-pad variant (TS613IDW) achieves R_thjc = 16°C/W and P_max = 2000mW at 25°C - critical for sustained 160mA output into 25Ω.

Key Specifications

Pinout & Package

TS613ID is housed in an 8-pin SO8 plastic micropackage (JEDEC MS-012AC) with exposed thermal pad on the underside (TS613IDW variant). The exposed pad is electrically isolated and intended for connection to –V_CC copper pour to enhance thermal dissipation (R_thja = 60°C/W).

FAQ

Can TS613ID operate from a single +12V supply?

Yes - the TS613ID supports single-supply operation when biased at mid-rail (e.g., +6V) using a resistor divider or active virtual ground. Its input common-mode range extends to (VCC+) –1V and (VCC–) +2V, and output swing reaches ±4.5V into 25Ω at ±6V, enabling full-scale differential signaling from +12V rails.

What is the purpose of the exposed thermal pad on TS613IDW?

The exposed pad on TS613IDW is electrically isolated from all pins and serves solely as a thermal conduction path. It must be soldered to a PCB copper area connected to –V_CC to achieve R_thja = 60°C/W and sustain 2000mW power dissipation - essential for continuous 160mA output into 25Ω loads in ADSL line drivers.

Does TS613ID meet ADSL G.992.1 upstream line driving requirements?

Yes - the TS613ID is explicitly characterized for ADSL upstream line driving: it delivers 12.4Vpp differential output into 100Ω line (via 1:2 transformer), achieves –77dBc IM2/IM3 at 70/80kHz, supports 130kHz bandwidth, and maintains stability with 25Ω//15pF loads - all aligned with ITU-T G.992.1 Annex A specifications.

How does TS613ID handle channel crosstalk in dual-driver configurations?

TS613ID provides –40dB channel separation at 1MHz, measured as XTalk = 20log(V2/V1) with 25Ω loads. This isolation prevents upstream signal coupling between channels in differential line driver topologies, preserving signal integrity in compact ADSL RT PCB layouts where physical spacing is constrained.
