Product details
Overview
TS652ID from STMicroelectronics is a dual-channel differential digitally controlled variable gain amplifier (VGA) with 4-bit programmable gain from –9 dB to +30 dB in 3 dB steps, 52 MHz small-signal bandwidth at +18 dB gain, 4.6 nV/√Hz input voltage noise, and 90 V/µs slew rate. It operates over –40°C to +85°C in SO-14 package and is designed for preamplification and automatic gain control in ADSL line receivers.
For engineers reviewing the TS652ID datasheet, TS652ID pinout, TS652ID application, or TS652ID equivalent, key selection criteria include guaranteed gain monotonicity, dual-channel matching (<1 dB gain mismatch), power-down mode (150 µA quiescent current), ±6 V supply operation, and high common-mode rejection in differential signal paths.
Technical Context
The TS652ID integrates two independent signal chains, each comprising a low-noise first stage (0–18 dB gain) and a second-stage gain/attenuation block (–9 to +12 dB), enabling precise composite gain control. Its CMOS-compatible 4-bit digital interface (GC1–GC4) directly sets total gain without external decoding logic.
It supports both dual-supply (±6 V typical) and single-supply (+12 V) configurations via AGND biasing at VCC/2; input impedance is 100 kΩ || 5 pF, output drives 500 Ω loads, and power-down mode isolates outputs with >80 dB isolation at 1 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Range | –9 dB to +30 dB in 3 dB steps; monotonic by design ensures predictable signal scaling across all codes. |
| Small-Signal BW | 52 MHz @ +18 dB gain (RL = 500 Ω, CL = 15 pF); enables broadband ADSL upstream/downstream channel support. |
| Input Noise | 4.6 nV/√Hz @ 100 kHz, AV = +30 dB; optimized for low-noise preamplification of weak DSL signals. |
| Slew Rate | 90 V/µs (gain-independent); supports fast transient response for multi-carrier modulation waveforms. |
| THD | H2 = –70 dBc, H3 = –93 dBc @ 150 kHz, 1 Vpeak, AV = +30 dB; meets ADSL spectral purity requirements. |
| Power-Down Current | 150 µA; reduces system standby power while maintaining channel isolation >80 dB up to 10 MHz. |
| Supply Voltage | ±6 V (dual) or +12 V (single); flexible rail configuration for legacy and space-constrained DSL front-ends. |
Pinout & Package
TS652ID is housed in a 14-pin plastic micropackage (SO-14) with standard SOIC footprint (8.55–8.75 mm × 5.8–6.2 mm, 1.27 mm pitch). Pin 1 is top-left corner (marked dot), pin 14 is top-right.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | +Vcc2 | Positive supply for Channel 2 amplifier; decoupling required near pin for stability. |
| 2 | Input 1 | Inverting input of Channel 1; differential pair with Pin 3; high-Z (100 kΩ || 5 pF). |
| 3 | Input 2 | Non-inverting input of Channel 1; forms differential input pair with Pin 2. |
| 4 | –Vcc | Negative supply rail (dual supply) or GND reference (single supply); shared across both channels. |
| 5 | DGND | Digital ground; separate from AGND to minimize digital switching noise coupling into analog path. |
| 6 | GC1 | LSB of 4-bit gain control word; CMOS-compatible (0.8 V / 2.0 V thresholds); latched on rising edge. |
| 7 | GC2 | Bit 2 of gain control word; synchronous with GC1–GC4; no internal pull-up/pull-down. |
| 8 | Output 1 | Differential output of Channel 1; capable of driving 500 Ω load with <1% THD up to 150 kHz. |
| 9 | AGND | Analog ground; must be tied to mid-supply (VCC/2) in single-supply mode; critical for CMRR. |
| 10 | Power Down | Active-high enable; asserts power-down mode when ≥2.0 V; output impedance rises to 100–150 kΩ. |
| 11 | +Vcc1 | Positive supply for Channel 1 amplifier; independent routing recommended for PSRR optimization. |
| 12 | GC3 | Bit 3 of gain control word; timing-critical only during gain transitions; no glitch filtering. |
| 13 | GC4 | MSB of gain control word; determines coarse gain range (e.g., codes $1100–$1111 fix +27/+30 dB). |
| 14 | Output 2 | Differential output of Channel 2; matched to Output 1 for <1 dB inter-channel gain error. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent channels | Matched gain (<1 dB), offset (6 mV max), and bandwidth ensure balanced differential signal processing in ADSL line cards. |
| Guaranteed gain monotonicity | No gain reversal across all 16 control codes; eliminates signal distortion during dynamic AGC updates. |
| Low-noise architecture | 4.6 nV/√Hz input voltage noise + 1.5 pA/√Hz input current noise; optimal for source impedances <3 kΩ. |
| High-output drive capability | Drives 500 Ω loads at full swing with <–70 dBc harmonic distortion; eliminates need for external buffer stages. |
| Flexible supply operation | Supports ±6 V dual supply or +12 V single supply with internal bias network; simplifies board-level power design. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential VGA applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8367ARUZ | Single-channel, 45 dB gain range (–2.5 to +42.5 dB), 750 MHz bandwidth, 1.25 nV/√Hz noise, requires external gain control DAC. | Lacks dual-channel integration and guaranteed monotonicity; better suited for RF IF gain control than baseband DSL. | Select when ultra-wide bandwidth (>100 MHz) and lower noise dominate over channel matching and digital control simplicity. |
| LMH6514MA | Dual-channel, 30 dB gain range (–10 to +20 dB), 400 MHz bandwidth, 8.5 nV/√Hz noise, analog voltage-controlled gain. | Requires precision external DAC and op-amp for gain programming; no native power-down mode. | Choose when analog gain tuning is preferred and higher bandwidth justifies increased noise and layout complexity. |
Compared with AD8367ARUZ and LMH6514MA, the TS652ID delivers tighter dual-channel matching, integrated digital control, guaranteed monotonic gain, and lower noise in the ADSL band-making it uniquely suited for cost-sensitive, space-constrained DSL line receiver designs requiring deterministic gain behavior.

FAQ
What is the maximum input signal level for TS652ID at ±6 V supply?
At ±6 V supply, the maximum input signal swing is ±4.5 V peak (–VCC + 1.5 V to +VCC – 1.5 V) due to common-mode input range limits of the first-stage amplifiers. Exceeding this risks clipping or distortion. The small-signal bandwidth remains stable up to this level, but slew-rate limiting begins above ~10 MHz for large transients.
Does TS652ID support true single-supply operation with AC-coupled inputs?
Yes - TS652ID supports single +12 V operation using AGND (Pin 9) biased at +6 V via resistor divider (e.g., two 7.5 kΩ resistors). Inputs must be AC-coupled with 1 µF series capacitors; the internal bias current (8 µA per channel) sets the DC operating point. This configuration maintains full differential functionality without performance degradation.
How does gain monotonicity impact ADSL automatic gain control (AGC) loops?
Guaranteed monotonic gain ensures that each incremental increase in the 4-bit control word produces strictly increasing output amplitude - eliminating "gain dips" or non-monotonic steps that could destabilize closed-loop AGC algorithms. This allows deterministic convergence and avoids oscillatory behavior in real-time line adaptation.
Can TS652ID's power-down mode be used for channel muting in time-division systems?
Yes - asserting Power Down (Pin 10 ≥ 2.0 V) places both outputs in high-impedance state (100–150 kΩ || 5 pF) with >80 dB isolation up to 10 MHz, making it suitable for TDD-based DSL protocols. Recovery time is <1 µs, enabling rapid channel switching without external switches or relays.
