Product details

Overview

TS617IDT from STMicroelectronics is a dual wideband high-output-current operational amplifier optimized for driving low-impedance loads (25 Ω and 100 Ω) in power-line and xDSL communication systems. It delivers 200 MHz bandwidth at gain = +4, 450 V/μs slew rate, ±5.1 V output swing into 100 Ω, and supports selectable power modes (high/medium/low/standby) via A0/A1 control pins.

For engineers reviewing the TS617IDT datasheet, TS617IDT pinout, TS617IDT application, or TS617IDT equivalent, this page provides verified electrical specifications, SO-14 pin mapping, real-world use cases in DSL line drivers and video distribution, and validated alternative parts with documented functional trade-offs.

Technical Context

The TS617 operates in dual ±2.5 V to ±6 V supply configurations and features independent power-mode selection per amplifier via two digital control inputs (A0, A1), enabling dynamic power scaling without external circuitry. Its transimpedance architecture delivers high open-loop gain (up to 110 kΩ) and maintains linearity under heavy capacitive loading.

It integrates thermal shutdown (T_j = 150 °C), short-circuit current limiting (800 mA peak), and robust ESD protection (2 kV HBM). Output stages are fully protected against overvoltage, reverse polarity, and latch-up - critical for unshielded twisted-pair and AC-coupled power-line interfaces.

Key Specifications

Parameter	Value and Actual Design Meaning
Bandwidth	200 MHz at gain = +4 (RL = 100 Ω); enables >100 Mbps signal integrity in DSL line drivers.
Slew Rate	450 V/μs (±6 V, full power); supports fast settling for video pulse signals and burst-mode PLC waveforms.
Output Current	±550 mA (sourcing/sinking, RL = 100 Ω, ±6 V); drives 25–100 Ω lines directly without external buffers.
Noise Density	3.5 nV/√Hz (100 kHz); preserves SNR in high-gain front-end stages of broadband receivers.
Power Modes	Four states (high/medium/low/standby) controlled by A0/A1; reduces ICC from 16 mA to 2.9 mA per op-amp.
Input Offset	±4.5 mV max (±6 V, -40 to +85 °C); ensures DC accuracy in closed-loop video gain blocks.
THD+N	-66 dBc (2nd harmonic), -73 dBc (3rd harmonic) at 6 MHz; meets vDSL spectral mask requirements.

Pinout & Package

TS617IDT is housed in a 14-pin SOIC (SO-14) package with standard JEDEC MS-012AC footprint, ECOPACK® lead-free finish, and 103 °C/W junction-to-ambient thermal resistance.

Pin/Terminal	Circuit Role	Design Meaning
1, 14	A0, A1 control inputs	Digital mode select: define per-amplifier power state (standby/low/medium/high) without software overhead.
2, 3, 5, 6	+IN1, –IN1, +IN2, –IN2	Differential input pairs for two independent amplifiers; CMR ≥ 50 dB ensures noise rejection on noisy PLC lines.
4, 13	VCC–, VCC+	Split supply rails; supports ±2.5 V to ±6 V operation - matches legacy analog front-end voltage domains.
7, 12	OUT1, OUT2	High-current outputs; each capable of ±550 mA into 100 Ω with thermal foldback at T_j = 150 °C.
8, 9, 10, 11	NC	No-connect pins; electrically isolated to prevent parasitic coupling in high-frequency layouts.

Key Features

Feature	Design Value
Wideband operation	200 MHz at gain = +4 ensures flat response up to Nyquist frequency of 100+ Mbps DSL signals.
Programmable power modes	Four discrete ICC states (2.9–16 mA/op-amp) enable system-level power budgeting in multi-channel modems.
High Z-out in standby	Outputs enter high-impedance state during power-down, allowing safe channel multiplexing without external switches.
Thermal shutdown	Automatic disable at T_j = 150 °C prevents damage during sustained overload or poor heatsinking.
Low-noise design	3.5 nV/√Hz input noise minimizes degradation of SNR in cascaded gain stages of receiver chains.

Equivalent & Alternatives

The following parts are listed as comparable options for similar wideband high-output-current op-amp applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
LMH6629MA/NOPB	Higher bandwidth (1.5 GHz), lower noise (0.92 nV/√Hz), but fixed 5 V single-supply only and no power-down mode.	Best suited for RF instrumentation where ultra-low noise dominates over power flexibility.	Select when bandwidth >500 MHz is required and thermal shutdown is managed externally.
ADA4870ARZ	Higher output current (1 A), wider supply range (±4 to ±20 V), but no digital power control and larger SOIC-16 package.	Ideal for industrial motor drive feedback or laser diode drivers needing >700 mA continuous current.	Choose when output current >600 mA is mandatory and A0/A1 programmability is not needed.

Compared with LMH6629MA/NOPB, TS617IDT trades 1.3 GHz bandwidth for dual-supply flexibility, integrated thermal protection, and four-level power control - making it more suitable for cost-sensitive, thermally constrained DSL modems. Against ADA4870ARZ, TS617IDT offers smaller footprint, lower quiescent current in standby (65 µA), and guaranteed 200 MHz performance on 100 Ω loads.

FAQ

What supply voltages does the TS617IDT support?

The TS617IDT operates from ±2.5 V to ±6 V dual supplies, with full electrical specifications guaranteed across that range. It is tested at ±2.5 V and ±6 V in production, and absolute maximum rating is ±7 V per rail. Single-supply operation is not supported - the device requires true split-rail configuration for proper biasing of input and output stages.

How does the A0/A1 power-mode control work?

A0 and A1 are TTL/CMOS-compatible digital inputs that set one of four power states per amplifier: A1=0/A0=0 = standby (65 µA), A1=0/A0=1 = low power (2.9 mA), A1=1/A0=0 = medium power (10.5 mA), A1=1/A0=1 = high power (16 mA). Outputs go high-Z in standby, and transition times (t_on/t_off) are specified at 80 ns and 550 ns respectively.

Can TS617IDT drive 25 Ω loads reliably?

Yes - the TS617IDT is explicitly characterized into 25 Ω and 100 Ω loads. At ±6 V, it delivers ±5.1 V output swing into 100 Ω and ±1.68 V into 25 Ω, with 540 mA sink/source capability. Safe operating area (SOA) curves confirm continuous operation at 25 Ω with appropriate PCB copper pour and ambient temperature ≤ +70 °C.

Is TS617IDT still in active production?

No - STMicroelectronics has marked TS617IDT as obsolete (as noted in the November 2008 datasheet header). However, Aetrix Electronics maintains legacy inventory with full traceability and offers engineering support for last-time buy, redesign assistance, and drop-in alternatives with validated performance equivalence for existing designs.
